Application to the DIS field GROTH_00
We applied EMphot to the very deep NUV image in the GROTH field with Texp = 237ksec. The optical catalog and images for the priors are based on the CFHTLS deep survey (T0005 release). We restricted the prior’s sample to sources with UAB<26.75.
Image residuals :
After running EM, the distribution of the count rate residual (GALEX-EM image), shown in Fig 2a, is very close to the expected Poisson distribution (slightly wider) and does not show deviation in the wings.
