Detailed statistic of this training dataset

1. Data included

1.1 Photometry

GALEX fuv and nuv, SDSS 'ugriz', DES 'grizY', Spitzer chanel 1 and 2, UKIDSS 'YJHK'.

1.2 Astrometry

GAIA proper motion and parallax and NOIRLab Source Catalog (NSC) proper motion.

1.3 Time domain

SDSS light curves; NSC MAD variability metric

2. The extended Stripe 82 footprint:

RA	Dec
(-60, -43]	(-1.25, 1.25)
(-43, 0]	(-2, 2)
(0, 45]	(-7, 5)
(45, 60)	(-1.25, 1.25)

Note: The non-AGN variables catalog only goes from -43 degree to 45 degree in RA and -1.25 degree to +1.25 degree in DEC, for the purpose of avoiding areas of high stellar density.
