The session will start with a very brief recap of the videos above - more of a reminder than a substitute for the videos themselves. Then we are planning to have short presentations from each of the science collaborations, a comment on their status as we go to the next phase of survey strategy development – community feedback to the SCOC.
Are there any issues, missing simulations or missing metrics for evaluating the survey strategy?
How is your collaboration placed in terms of this next phase - what resources are available or lacking?
1:53 List of general SAC questions
3:12 Brief overview of simulation families and groups
9:50 Start of in-depth coverage of each family
44:55 Go to community.lsst.org for more!
It would be immensely helpful for us to understand how this material helped you understand what is going on in the survey strategy process or what is missing. There is a really wide range in where people are coming from – either knowing nothing about the general plan for the LSST or having followed the evolution of this planning for many years. It’s easy for us to miss areas where people have questions.
Hi Lynne and Peter, thanks for posting the report.
Question for you as I was checking the metrics - page 14 on the SRD metrics. Understandably the high level SRD metrics of area, number of visits and errors on parallax/pm are considered. But you also have an SRD metric of “number of rapid revisits (on timescales of between a few to 40 sec) per point on sky”. Is that a typo ? Do you actually mean minutes ?
If it is seconds, then difficult to understand how this plays with snaps and visits (for moving object identification)
We don’t usually talk much about the rapid revisit requirement. It typically gets met because neighboring pointings have an overlap area, so as long as we keep most of the slews short, we meet the requirement.
We haven’t experimented much with how dense/sparse the sky tessellation is, mainly because fiddling with it too much would probably make us fail the rapid revisit requirement.
