Message:

• add concept of saddlePoints to peaks (not actually used in the end)
• add tmp flags to mark sources for analysis or not in psphotStack
• autocode the pmSourceIO_CMF_PS1_* functions
• use 1D gauss approx for convolution in PCM fitting
• added pmSourceExtFitPars (not actually used)
• in model guess, use 1st radial moments to define size (if it exists)
• include PSF_INST_MAG, AP_MAG, KRON_MAG in xfit output
• fix the position for extended source fits (avoid instability)
• Sersic-like models (incl. Exp and Dev) use Reff, not sigma; conversion tools need to respect this
• only use a single pass on the centroid (unwindowed, but limited to 1.5 sigma radius) - this avoids moving the centroid because of nearby neighbors
• use symmetrical averaging (geometric mean) to calculated 1st radial moment (and avoid neighbor biases), do not use symm. averaging for the flux
• fix the integration of the sersic, pgauss, and related model functions.
• fix the central pixel to have the full flux for sersic-like models (interpolated value)
