    75  * with more current ipp-20121026 tag (conv + unconv refstack): conv/unconv are close and the difference between exposures is smaller ~0.4 vs 0.6 but maybe not in the proper direction, the PSF_ offset from SMF is still ~0.5 (brighter). AP_MAG similar to orig diffim and offset from SMF ~0.2 mag (fainter).

     76 * with ipp-20120802 tag and new seed (conv + unconv refstack): conv/unconv are close and the difference between exposures is smaller ~0.4 vs 0.6 but maybe not in the proper direction, the PSF_ offset from SMF is still ~0.5 (brighter). AP_MAG similar to orig diffim and offset from SMF ~0.2 mag (fainter).

    87  * with older ipp-20110622 tag (conv only) that was active when photometry "looked better" last year (see example mag plot for TNO145452 below): clearly something changed since with the PSF measure, the difference is smaller ~0.1 mag but the offset from the SMF is larger 0.3 (fainter).
     88 * with more current ipp-20121026 tag and same seed as original WSdiff (conv + unconv refstack):
