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?

Agenda

• Introductions (everybody: 5 mins)

  • Sarah Casewell – stellar and exoplanet

  • Adam McMaster – microlensing

  • Dan Ryczanowski – strong lensing

  • Xinyue Sheng – supernova classification

  • Iair Arcavi – tidal disruption events

• Goals today (Andy: 5 mins)

• Lasair overview (Roy: 10 mins)

  • published paper

• Rubin schedule context (Stephen: 10 mins)

• Current key issues (Roy: 20 mins)

• General discussion (Everybody: 20 mins)

  • Features

    • 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
