|The notch in differential reliability...||And it's cause - artifacting around bright point sources.|
Difference between instrumental and true magnitude.|
Because the shape of the PSF changes as a function
of source brightness, DAOPHOT under/overestimates
the source brightness.
Red sources are true matches detected in the raw coadd.|
The green circles are new matches made after the original positions
were scrambled. In theory, no new matches should have
occurred - these six are the result of randomly matching sources
meeting our position and brightness constraints.
