  1. a new "staticsky" distribution component : this is the method by which we will be distributing the results from the full photometry analysis of the static sky images.
- 1. Full extended source analysis!  psphot is now able to produce acceptable measurements of all of the extended source parameters on our list.
+ 2. Full extended source analysis!  psphot is now able to produce acceptable measurements of all of the extended source parameters on our list.
    a. for all sources, we are now including Kron parameters (Kron flux and error in an aperture 2.5 times the first radial moment (R1), plus the flux within 1 times R and 4 times R1, as well as the value of R1.
-   a. in the static sky analysis, for all sources we now report the radial aperture measurements (this was available in the earlier MD04 example set).
-   a. Petrosian and elliptical surface brightness profiles for a subset of extended sources (S/N above some cut off to be defined, probably based on galactic latitude)
-   a. PSF-convolved model fits for a subset of extended sources for Exponential, DeVaucouleur, and Sersic models.
- 1. fixed the forced photometry non-negative flux bug
- 1.  added some other new stats:

+   d. PSF-convolved model fits for a subset of extended sources for Exponential, DeVaucouleur, and Sersic models.
+ 3. fixed the forced photometry non-negative flux bug
+ 4.  added some other new stats:
   a. for PSF fits, we now have "psfWeightNotPoor" and "psfWeightNotBad" : the first gives the fraction of psf-weighted unmasked pixels considering any mask bits (except the internal 'mark' bit), while the former considers only 'bad' mask bits -- these are written to QF_PSF and QF_PSF_PERFECT in the CMF / SMF files.  This may help to exclude false sources in subtracted burn regions (SUSPECT mask bit) or sources too close to a mask edge (CONV.POOR mask bit).
-  a. raw aperture magnitudes (in addition to the curve-of-growth corrected version) for PSF measurements.
-  a. in diff images, we now have several additional statistics related to the proximity of a diff detection to an input image source: DIFF_R_P, SN_P : distance and S/N of nearest bright source in the plus image, DIFF_R_M,SN_M : same for the minus image.
-  a. for PSF sources, we have added several higher order moments: MOMENTS_M3C,S (third moments cos & sin theta), and same for 4th moments.
- 1. somewhat better CR / EXT tests, including use of Kron magnitude as test for source size (CR vs EXT) instead of PSF-based aperture. (though these are not yet reported as a probability).
- 1. save the radial profile aperture sizes in the headers
- 1. swap read order in dvomerge to loop over the available input tables and merge them with existing output tables
- 1. allow dvomerge to operate on only a region of the sky
- 1. update to dvomerge to allow different average photcodes in the inputs and the output database.
- 1. some important issues in ppSub that were resulting is somewhat poor matches when the IQ difference between the two images was large:

+ 10. some important issues in ppSub that were resulting is somewhat poor matches when the IQ difference between the two images was large:
   a. ensure masked pixels are NANed in output diff image
   b. define separate penalties for each image (based on their fwhm values)
