Residuals from the calibration fit ( PSF magnitude minus aperture magnitude of the catalog) for CCD #13, band rM in field D1. Each point is a tertiary star. Those marked with open symbols were excluded from the fit based on cuts on rms, magnitude, and number of observations. The fit is performed iteratively with a 2.5σ outlier rejection.
