Note that session recordings are linked to the title of each session.

Session 1 (9:00AM-10:50AM): Introduction to SCOC and Call for Cadence Notes

  • Workshop goals and outline (10 min)
  • SCOC introduction, goals, decision process, and timeline (10 min)
  • Information about the SCOC call for Cadence Notes and their expected content (20 min)
  • Introduction to (the tool for breakouts, 10 min); map:
  • Breakout groups (at Gather town, see slack scoc2020): Science Collaborations and their SCOC liaisons (60 min)

  Break: 10:50AM-11:00AM


Session 2 (11:00AM-1:00PM): Existing Survey Cadence Simulations

    • Introduction to survey cadence simulations (includes brief justification for the baseline cadence, e.g. its footprint definitions, and links to pre-recorded more detailed material and published papers and other docs).  Slides:
    • Overview of existing cadence simulation families (white papers rationale, high-level summaries)  Slides:
    • Breakout groups (at Gather town, see slack scoc2020): Science Collaborations and their SCOC liaisons 


    Session 3 (9:00AM-10:50AM): Analysis of Existing Survey Cadence Simulations

      • Overview of core MAF science metrics - what they are and how they vary with survey strategy, plus missing metrics. Slides:
      • Introduction to basic MAF and introduction to Jupyter Lab @ DataLab (resources to enable post-workshop MAF-like analysis). Slides:  Detailed information about Jupyter Lab @ DataLab:
      • Breakout groups (at Gather town, see slack scoc2020 for password): split by main “open questions”: i) footprint definitions and area vs. visit count tradeoffs, ii) optimal exposure time and observing time allocation per band, iii) temporal sampling strategies, iv) DDF strategies

        Break: 10:50AM-11:00AM


      Session 4 (11:00AM-1:00PM): Open House Discussion

        • What did we learn so far from existing MAF metrics? (report progress relative to COSEP)  Slides:  
        • Contributed 1-slide 2-min presentations of various ideas not captured in Cadence Notes  

                Slides  Eric Feigelson:   Gordon Richards:   Jean-Charles Cuillandre:   Xiaolong Li:  Fabio Ragosta   Rosanne Di Stefano:   Rachel Street: Dan Scolnic Yasaman Homayouni  Will Clarkson

        • Open questions and tradeoffs (rationale for the questions asked in the Cadence Notes call)
        • The best ways to support people using Jupyter Lab @ DataLab (office hours vs. documents)
        • Remaining steps in SCOC’s decision process, comments and suggestions, feedback on Cadence Notes call
        • AOB (any other business)

        All sessions will be recorded and made publicly available, with real-time minutes written by SCOC members.
