  * RA_DEG, DEC_DEG renamed RA, DEC to match apparent naming policy
  * *_SIG renamed *_ERR to be more clear
- * ANG, ANG_SIG, LEN, LEN_SIG spelled out as ANGLE, ANGLE_ERR, LENGTH, LENGTH_ERR
+ * ANG, ANG_SIG, LEN, LEN_SIG removed; these can be calculated from the moments
  * FLUX, FLUX_SIG renamed MAG, MAG_ERR since IPP writes magnitudes
  * FLAGS added to allow additional weeding out of bad detections
  * DIFF_SKYFILE_ID added to allow trace back to IPP diff skyfile, for postage stamps

+ * STARPSF renamed EXT_SIGNIFICANCE to be more clear
+ * Added PSF_CHI2, PSF_DOF, CR_SIGNIFICANCE, PSF_MAJOR, PSF_MINOR, PSF_THETA, PSF_QUALITY, PSF_NPIX, MOMENTS_XX, MOMENTS_XY, MOMENTS_YY for more complete data on each detection
+ * Added N_POS, F_POS, RATIO_BAD, RATIO_MASK, RATIO_ALL for better weeding out of bad subtractions
