+ I have finished another iteration on source size analysis.  I feel
+ fairly confident of the extended source and CR identifications.  They
+ are not perfect, but they are in pretty good shape.  The CR IDs use
+ the moments to find things smaller in one dimension than a PSF, while
+ the EXT is set for things larger than a PSF in one dimention. 
+
+ There still seems to be some trouble with SATSTARS : these are being
+ set for sources which are fainter than the SAT limit -- I'm not sure
+ if this is due to the quality of the PSF fit or if they really are
+ SAT, but have integrated fluxes lower than expected (underfitted in
+ PSF).
