 Some notes on what this database contains:
 
-* all 3pi data taken since the start of demo month (2010/2/12) through last week (2011/2/1).
-* 2MASS detections matched to all objects
-* average fields for grizy and JHK (eg, avextract g i J K would work)
-* zero point calibrations for the PS1 data come from the synthetic photometry database.
-* astrometric calibration is the default in-line calibration relative to the 2MASS frame
-* average magnitudes use a weighted mean, and skip detections that have PSF_QF < 0.85 (excessively masked objects).  there is no iterative clipping, however.

 In addition, there are 4 bit flags available in the average table for
 each object to give a hint at quality and extendedness:
 
-* for all PS1 detections, the detection is considered 'extended' if (mag_psf - mag_ap > 0.5) 
-* if the number of 'extended detections' exceeds the number of 'psf-like' detections, the object is flagged as "PS1 extended" (objflag & 0x01000000)
-* if any of the detections have PSF_QF  > 0.85, then the object is considered "PS1 good" (objflag & 0x04000000)
-* similarly, if the 2MASS J-band flags indicate the source is extended, the object is considered "2MASS extended" (objflag & 0x02000000)
-* if the 2MASS J-band detection is significant (**), the source is considered "2MASS good" (objflag & 0x08000000)
+ * for all PS1 detections, the detection is considered 'extended' if (mag_psf - mag_ap > 0.5)

 note: A significant 2MASS source means their field ph_qual is one of the
