Description
As of the July 2009 MD data release, x_psf_sig and y_psf_sig look badly calculated for faint objects. A histogram of x_psf_sig vs psf_inst_mag, for instance, reveals a discontinuity in x_psf_sig, where suddenly errors get a hundred times worse. I mentioned this a while ago and think a fix had already happened or was in the works. However, I got bitten by it today and figured I'd make a ticket...
