Changeset 24206 for trunk/psModules/src/imcombine/pmPSFEnvelope.c

Timestamp:

Author:

Message:

Fitting a trend of chi^{2 as a function of flux was often failing when fitting a PSF for the fake sources in pmPSFEnvelope (because all sources have similar flux). Made this part optional via an entry in pmPSFOptions (default true).}
