- * with more current ipp-20121026/trunk tag (conv + unconv refstack): conv/unconv are closer, but difference is smaller ~0.3 vs 0.6 and the offset from SMF is still ~0.5 (brighter). AP_MAG similar to orig diffim and offset from SMF ~0.2 mag brighter.
+ * with more current ipp-20121026/trunk 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).

- * 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 (brighter).
