The photometric depth depends on various factors like number of exposures used, total exposure time, seeing, cloud coverage, and crowdedness. Therefore PS1 does not have a uniform depth (see spatial depth maps below), but overall due to a real effort to apply a PS1 Observing strategy that maximizes the uniformity, the differences in depth are in general only a few tenths of magnitude.
