 Notes on psphot
+
+2005.09.06
+
+  I have built a working version of PSPhot using my own copy of the
+  pmObjects.[ch] files.  I need to minimize the difference between the
+  v0.7.0, v0.5.0, and my own version of pmObjects.c
+
+  changes v0.5.0 / v0.7.0 / EAM
+  - changed all ps* to pm*
+  - fixed naming for local static functions (eg modelFree not p_psModelFree)
+  - dropped all hard-coded model names (vs v0.7.0)
+  - using current psMemSetDellocator name
+  - added noise image to pmSource
+  - converted old asserts to new asserts (PS_.._CHECK..)
+  - add return from error in pmFindImagePeaks
+  - allow isItInThisRegion to have NULL region (true)
+  - fixed subImages to correspond to region definition (end is
+    exclusive) in LocalSky and SetPixelCircle
+  - dropped old, redundant code in pmSourceLocalSky
+  - fixed pmSourceMoments use of mask (0 is valid, not 1)
+  - added pmSourceMoments validity tests (numPixels, Sum, centroid shift)
+  - added correction for Sxy (XY/Sum - x*y)
+  - added pmSourcePSFClump function (and pmPSFClump structure)
+  - allow missing sources in pmSourcePSFClump (not all peaks yield
+    sources)
+  - moved pmSourceRoughClass metadata lookups out of inner loop
+  - added saturated pixel test using pmImageCountPixelMask
+  - various redefinitions of initial classes
+  - dropped old, redundant code in pmSourceSetPixelsCircle
+  - mask image set to type psU8 (was psF32)
+  - abstract object model functions for pmSourceModelGuess
+  - converted evalModel to a public function psModelEval, modified params
+  - pmSourceFitModel operates on a specified model
+  - pmSourceFitModel had option to apply/ignore PSF information
+  - pmSourceFitModel calculates yErr
+  - pmSourceFitModel calculates the covariance matrix
+  - added paramMask to pmSourceFitModel 
+  - pmSourceFitModel_EAM uses covar to carry in beta and param
+    limits...
+  - pmSourceFitModel requires solution to stay within image
+  - pmSourceFitModel calculates and saves chisq, nIter, nDOF
+  - pmSourceFitModel uses GaussNewtonDelta for frozen params
+  - added mask to pmSourceAdd, pmSourceSub
+  - model abstractions in pmSourceAdd, pmSourceSub
+  - fixed 'center' option in pmSourceAdd/Sub
+
+  - pmSourceFitModel calculates sqrt(var), psMinimize calculates sq(sqrt(var))
+  - pmSourceContour is using the model flux, not the image flux
+  - does psImageAlloc zero the image?  if so, drop init routine
+    from pmSourcePSFClump
+  - pmSourceRoughClass uses RDNOISE, GAIN to calculate SN: should use
+    the source->noise image? part of pmSourceMoments?
+  - pmSourceMoments_EAM uses macro for checkRegion
+  - pmObjects_EAM.c uses some hardcoded mask values (LocalSky)
+  - why does LocalSky_EAM not need subImageMask->col0 = subImage->col0??
+  - psGetRowVectorFromImage should be in psLib (in psLibUtils)
+  - pmSourceSetPixelsCircle and pmSourceLocalSky probably could use
+    the psImageMaskRegion, etc functions.
+  - pmSourceSetPixelsCircle uses a hard-coded mask value
+  -
