Please include information about our photometric depth in the validation suite. One way to do this (which would be a good start!) would be to look at the properties of the sky objects in the coadds; both the scatter of the PSF and aperture fluxes and their scatter in units of the quoted errors are interesting.
As part of the drill-down, we should be able to compare the scatter of the measurements of the same places on the sky from individual visits (this will require either remeasuring on the visits, or using a catalogue of sky objects from e.g. a previous processing of the data)
