Live discussion notes

Live notes at meeting as per usual Roy style.

Notes:
When we are happy with this meeting page, we can link it from the top-level meetings page and then circulate.
Suggest we show slides but link these into this page after the meeting.
It needs to be clear what we are asking them
- quick free form comments on some of the below
- suggestions for what to prioritise for full discussion at next meeting
- but also a few specific questions (do you think X or Y?)

The topics below are a great start but too complicated for a 50 min total discussion.. need to headline them, and turn them into questions

Should we include the list of topics on this wiki page, or just on Roy’s slides?

Roy’s suggested discussion topics

• ZTF continuation

  • We are not paid for ZTF

  • 2 codebase, ZTF and LSST websites, same documentation, same API

• Onboarding new users

  • Why choose Lasair?

  • /wiki/spaces/LUSC/pages/3467804931

  • Intro materials

    • Quickstart and serious videos and joky video

    • Text/video/notebook?

    • Menu of sample filters to choose and modify?

• Queryable attributes copied from LSST schema

  • Proper motion/parallax, error, covariance?

  • Current object attributes and all LSST object attributes

• Lightcurve schema and features

  • Flux vs magnitude (difference flux is often negative!)

  • Existing LC features here and here

  • New features

    • Fastfinder

    • Colour from revisits?

    • Achromatic features?

• Kafka ecology

  • Consuming filter output

  • Annotating Lasair objects

  • Consuming Alerce and Fink

  • Rate-limited consumerFeatures

    • Parallax + error is wanted

    • Use box least squares for periodicity

    • Follow LSST with flux primary and magnitude available but secondary

  • Marshall notebook is useful

    • Adding extra information would be useful

    • How to make the marshall shared

  • How to find increased flux by 2% in all filters – microlensing

• Members discussion (Andy, Roy and Stephen temporarily leave: 10 mins)

  • Dan will be convener with Xingue as deputy

    • Check that Iair is OK with that

  • How to join multiple transient surveys

• Plans for next meeting (Andy: 10 mins)

  • Users meeting in Oxford Dec 9 with LUG meeting

Looks like Dan can edit the meeting pages
