How will Difference Image Analysis (DIA) work in LSST? This session will provide a brief overview of LSST DIA, technical pixel-level discussions of state-of-the-art image subtraction, selection of reference templates, and plans for testing and separation of real astrophysical events from artifacts. The Project will discuss current testing and validation plans. The Community will present lessons learned from previous and current surveys. An outcome of this session will be a list of specific testing requests and suggestions from the community.
Attention scientists and educators: we want your input! The EPO team has been hard at work developing interactive, online investigations for advanced middle school through college (Astro 101) students. These investigations address common topics taught in introductory astronomy classes while focusing on the LSST science pillars and capitalizing on the strengths of LSST data. Sample topics include variable stars, small Solar System objects, large scale structure, and mapping the Milky Way.
This session will consist of discussion among scientists interested in solar system research about making necessary preparations for doing solar system science with LSST data.
Overview of recent updates to the scarlet multi-band deblending package, diagnostics and results using the LSST stack, and presentations by other researchers to describe their experiences and suggestions for future scarlet upgrades.

The summit and base networks in Chile are still in construction but also in a pre-operations phase as we're already supporting connections for the coating chamber, M2, M1M3, PFlow and AuxTel. This session will provide an overall status of the networks at both sites and future challenges for the upcoming year, with special focus in connections for the Pier, Dome and the TMA.
Please contact Luis Corral lcorral@lsst.org if you want to contribute.
In this breakout session, we will share recent and current diversity and inclusion initiatives happening at the LSST Project, affiliate institutions, and science collaborations. Highlighted efforts will include but are not limited to an LSST diversity and inclusion topical interest group, the NSF-funded Multimessenger Diversity Network, an update on the LSST Code of Conduct, and best practices for hosting inclusive meetings.
Whether it is across a collaboration, at a conference, to the media, or to your friend, making your work understandable to others is important in achieving your goals. Communicating complex ideas does not come naturally to everyone, but is a skill that can be developed with a few basic tips and a little practice. In this session, I share simple tips you can apply immediately to improve the effectiveness of your communication and give you the opportunity to practice your new skills.
This session will consist of updates from Project personnel about current development of the Moving Object Processing System (MOPS) for LSST, and discussion between Project personnel and interested scientists about upcoming development of MOPS and other survey-related activities.
A significant amount of effort is being put into developing systems and software to allow more efficient followup of large transient surveys (e.g. Catalina, Pan-STARRS, ZTF, and especially LSST) and multi-messenger astronomy (MMA). This session will provide an update on these efforts and provide a forum for feedback and discussion. The components include event brokers, observation managers, automated observing systems, and data pipelines.
LSST provides IT services in Chile with a mix of IT north and IT south staff, including internet and intranet access, telephony, WiFi, network file systems, etc... for project staff (NCSA, SLAC, LSST or other collaborating institutions) it's important to understand these and be aware of the current policies and timing for some services to be provided, especially when your visit has some special requirements involving IT.
The DM Hack Sessions constitute a self-organized working space where DM developers and interested others are encouraged to work together on cross-team projects. Come ready with a project you want to work on, or just come to check out what others are up to.
We particularly hope that folks will use this time to work on the “Gen 3 Portathon”, which was introduced at the DM All Hands on Monday.
In this parallel session, we discuss ways that LSST can contribute to understanding the fundamental nature of dark matter (for a recent review, see https://arxiv.org/abs/1902.01055). The relevant techniques for probing dark matter (Milky Way substructure, strong gravitational lensing, galaxy clusters, low surface brightness galaxies, microlensing, etc.) cross multiple LSST science collaborations.
This session will focus on some less well known & studied instrument signatures, with discussion between Camera and DM on the details of these effects. Useful outcomes include: update to plans for laboratory images, assessment of needed algorithms and calibration data to correct, wider dissemination of the existence of these effects.
Agenda:
From strong lensing systems, to light echoes of historical supernovae, to streaking NEOs, what are special challenges with resolved variables and transients? This session discuss technical challenge in subtractions and characterization for variable and transient objects that are resolved in a single image. There will also be discussion of the benefits and complications of combining multiple images at the pixel level, with or without shifting, may yield additional sensitivity to new science.

This session will be used better detail the activities of commissioning the LSST Auxiliary Telescope Imager and Slitless Spectrograph) to give a quick status of the current state of telescope, instrument and general system readiness. Possible discussion points will include:
The project team has been busy flexing the scheduler to create new simulations based on guidelines from the SAC (and based on the Survey Strategy Whitepapers submitted last November). We will present some of the early results of this process, with several new simulations including rolling cadence simulations. We will talk about the plan for further survey strategy work up to the early 2020 deadline to pass these survey strategy evaluations over to the SCOC (the “Survey Cadence Optimization Committee”, a community-based committee set up by the LSST Operations Director).
This session will not be open for remote participation.
LSST Project Communications and IN2P3 Communications working meeting on upcoming collaboration areas including milestones, meetings, shipments etc. Naming will also be discussed. Output will be list of areas for collaborations and approximate dates. There will be no presentations given.
As we begin to analyze data from live LSST instrumentation, a reliable and well-understood set of tools for performing “QA” on all aspects of the DM system is essential. In this session, we will review progress on various aspects of that toolset. The agenda includes:

It's never too soon to learn how to write good requirements! Let's meet and discuss the importance of writing good requirements, guidelines for writing good requirements, and then break into groups and take a stab at it ourselves.
This will be an interactive session. 1/2 Presentation & 1/2 Workshop
Part 1: Presentation
- Why is it important to write a good requirement?
- Simple guidelines for writing good requirements
- Examples of good and bad requirements, and discussion on what makes a requirement "good" vs "bad".
This session will provide a hands-on opportunity for scientists to learn more about the work of the LSST DM Stack Club. The Stack Club, an on-going bi-weekly zoom meeting, has been taking place for about a year now. The goal of Stack Club is to facilitate learning the LSST processing software (the "LSST Software Stack") by working through community-built tutorial Jupyter notebooks, and then by extending those to do the things of use to the participant. All tutorial notebooks are built using the LSST Science Platform.
You will have the opportunity to edit this abstract if your suggested session is scheduled.
Evaluating the various simulated survey strategies is complex and involves many metrics. We will demonstrate the metrics currently being calculated on the various survey strategies and how they vary between runs. Then we hope to involve the community in a discussion covering (a) how accurate or complete are the metrics relevant to your science? (b) how can we weight different metrics together (or if considering groups of metrics separately, how do we separate them)? and (c) what is reasonable to present to the SCOC (Survey Cadence Optimization Committee)?
Wednesday, 1:30 - 3:00pm Pacific, Coronado II.
The Active Optics System will correct system aberrations introduced by gravity and temperature gradients in near real-time. This session will focus on the wavefront estimation component, where the wavefront is estimated from donut images on the corner wavefront sensors. We will discuss recent progress developing the curvature wavefront sensing technique and hear about alternative approaches based on optimization and machine learning.
Poster submissions from any and all workshop participants are welcome for this session, which will take place on Wednesday from 5-6pm in the Turquoise Foyer. Posters can represent LSST-related work, research, travel, or any other associated projects. Poster titles should please be submitted to Melissa Graham via email at your earliest convenience (mlg3k at uw dot edu). There will be a cash bar open in the foyer during the poster session.

9:00 - 9:05 - Daily updates
9:05 - 9:25 - Lightning Stories from across the project - Various project members
Our presentation will address three main topics. These three topics are linked to Safety's work in the Base Facility and Summit Site sites.
• Who we are: A brief account of who the members of the safety team are, their environment and the motivations they have in their careers.
• LPM18 Safety Policy and LPM 114 LSST Safety Plan, An explanation of how we have integrated these documents into the daily activities of the LSST sites, these two documents are considered the basis of our safety management.

In the first year of operations, LSST will not have full deep templates across the sky, and image subtraction without an Atmospheric Dispersion Corrector (differential chromatic refraction) means that we have to think carefully about constructing templates from images at different airmasses. The Project has already done leading investigations into understanding and modeling differential chromatic refraction.
By the mid-2020s gravitational wave event detections will have increasing precision locations on the sky. The LIGO+VIRGO+KAGRA 90% error footprints are expected to be on the order of the LSST field of view, for black hole binaries, neutron star black hole binaries, and neutron star binaries -- and the unexpected. With an investment of hours per selected event, LSST will be able to find the electromagnetic counterpart and pass the information quickly on to spectroscopic facilities.

An overview and status update of the DM middleware, including the current plans for moving to the PipelineTask and Butler Generation 3 systems.
(May need to be two sessions).
In this breakout we would explore scheduling early "data crunch" sprints. A "data crunch" sprint is where we invite members of the community and the project to come together for a week and analyze result of data processing through the LSST science pipelines. This would serve as a pattern for engaging the community in analyzing commissions and science validation data. The "data crunch" series would start with the DM processing of HSC data to develop familiarity and tooling within the LSST Science Platform frame work along with comparisons from independent analysis and code bases.

How do DIA Sources become DIA Objects? What DIA information will be available on 60-second, 24-hour, and yearly timescales, and how is the community planning on using it? What are the driving science use cases of the Prompt Data Products? There will be a particular focus on lightcurves. Lightcurves are at the heart of time-domain analysis, but there is no currently defined nominal data model for a lightcurve. Are there common lightcurve data objects that serve wide audiences, or are there different needs for transients and variables?
During the second part of this breakout we will discuss the effects of compressed schedule on system verification and science validation as well as the de-scope options and impacts. Finally we will work on the software tooling Workflow planning, from observations to analysis.
The purpose of this session is for members of the Galaxies Science Collaboration to collectively discuss progress, share ideas, develop a strategy for the future scientific direction of the SC. With commissioning data becoming available around a year from now, this meeting will be crucial for successfully fulfilling the scientific goals that the SC has laid out in its roadmap.
This session will present the current interconnection and orchestration approach in Chile for blending networks, physical servers, virtual machines, containers and the cloud together using tools such as APIs, Python, Puppet, Kubernetes, plus the challenges faced in the way to provide visibility, accountability and security.
A meeting of the SMWLV Science Collaboration to discuss our science plans and future road map. Please contact session organizer John Gizis [gizis AT udel DOT edu] with questions, suggestions, or to contribute content to this session.
