Completeness as fcn of seeing and depth

(Diego)

Tests carried out on MAG_AUTO only, as only for this magnitude a depth map was available.

For seeing estimate, the following maps (latest available sent to me by Eli) have been used respectively for the shallow and deep coadds:

SVA1_ERCOADSS_t1000_i_nside4096_oversamp4_FWHM_coaddweights_mean.fits

SVA1_ERCOADSS_all_i_nside4096_oversamp4_FWHM_coaddweights_mean.fits

The seeing (FWHM) in these maps is given in units of pixels. Conversion from pixels to arcsec was carried out by multiplying the values given by the maps by the median arcsec/pixel ratio measured for DECam: 0.264

The depth map was available for the shallower coadds only and for mag auto only (see SVA1 SN Field Shallow Coadds):
