CMMS (Computerized Maintenance Management System)

The CMMS is a Maintenance and Work Coordination Process, embodied in a set of project and Organizational level tools. The CMMS collects information from various tools and databases, and provides a consolidated view for assigning resources to tasks. Chiefly among these tasks are Maintenance activities, which must be coordinated with Construction, Science, Commissioning, and Engineering activities. Following are additional basic functions:

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.

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 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.

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. 

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.

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:

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.

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.

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". 

You will have the opportunity to edit this abstract if your suggested session is scheduled.

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.

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?

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.
