    7   * various changes to psphotstack (Gene/Bill know more)
    8   * various changes to dvo related stuff (Gene knows more, here's what heather remembers of the top of her head)
    9     * best qf_perfect, best sg_sep for dvo averages
    10     * does the right thing for nx=0 - mags are null
    11     * nframes has been fixed, now reports the correct value
    12     * nigel's "goofy mags" due to dvo having duplicates - should be fixed both in dvo and in ipptopsps

     9  * nigel's "goofy mags" due to dvo having duplicates - should be fixed both in dvo and in ipptopsps
     10  * Better modeling and subtraction of flux from very bright stars (subtract a smoothed radial profile) -- reduces number of false detections
     11  * do not allow negative fluxes for real detected objects in linear flux fit - improves measurements of nearby sources
     12  * use a mask to prevent detections on 2nd pass within 1" of detections from 1st pass
     13  * Changes to psphotStack object matching- reduces spurious sources
     14   * Require object be detected in 2 bands before creating sources for forced photometry (matched sources)...
     15   * ... Except if only detection is in y band perform forced photometry in
     16     all bands.
     17   * Drop matched sources for which aperture flux is not finite (This usually
     18     happens when the pixels in the matched band are totally masked)
     19  * Insure that NAN pixels in image and variance images are masked. This avoids several crashes that prevented some static sky analysis from completing for some skycells.
     20 * Better error handling in Kron radius measurements. This reduces spurious large values.
     21 * When psf matching fails for an input continue with the psphotStack analysis skipping the radial aperture measurements for the matched images in that band.
     22 * Perform psphotStack even if stacks are available for less than five filters in a given skycell.
     23 * Fix N_FRAMES measurement which was getting lost in the skycell calibration process.
     24 * In DVO correct an error in zero point application to the object level flux measurments
