In addition to tile dependence of S/G separation in the SN Fields, there is evidence of tile dependence of the psf model in the SN Field Coadds as demonstrated by the

In 100 x 100 bins in RA and dec, for each of the SN fields, plot the average in each of the bands for stars (CBDT algorithm of S/G challenge) with mag_psf < 22,  the following:

δ mag = mag_psf – mag_auto

where the quantities come from the SVA1_COADD_SNx database.
