SSO quantities for ops-rehearsals 3 and 4

Data are partitioned by (nside=32, ring ordering) healpixel. For each pixel there is a so-called “main file” and a flux file. The latter contains for each object only fluxes for lsst bands, the object id and the time (mjd) of the observation. The latter two fields may be used to join with the main file.

SSO main file

Name	Datatype	Units	Description
id	string	N/A	Unique object identifier
mjd	double	days	Time of observation
ra	double	degrees	Object right ascension
dec	double	degrees	Object declination
trailed_source_mag	double	N/A	Mag. normalization for SED
ra_rate	double	deg/day	RA rate of change * cos(dec)
dec_rate	double	deg/day	Declination rate of change
