How will LSST alert data differ from ZTF ?
...
In the 2nd and subsequent alerts, there will be forced photometry data, over 1 yr (SJS has to check if it’s 1 yr or full history). You will get 2 plots - one will be the magnitudes for >=3 sigma detections,
Image stamps will only be 6 x 6 arcsec.
Access to large image stamps of the target data are embargoed for 80 hrs (even to those with data rights). Access to the larger stamps from the reference images is not under the 80hr embargo but they are only available to data rights holders.
Some Discussion starting points for the breakout groups
User requirements for Lasair - what’s missing that your science needs ?
How to alert on interesting sources early - ML for lightcurves and classification ?
Cross-match catalogues : from watchlists to catalogues
...
Is documentation sufficient to learn how to use Lasair, and SQL and make queries ?
Questions raised
Is the forced photometry 1yr or full history ?
Saturation limit - what happens with m < 16 sources, are they even flagged ?
Real time x-match against Euclid - possible ?
How will a resolved PSF, such as a lensed SN be treated in the LSST real-bogus classification and will it be rejected with a simple RB cut ?
