# DVO Release 20120606

(up to [IPP Data & DVO Distribution](@WWWHOST@/index.php))

This directory contains the Nightly Science 3pi DVO database snapshot
from 2012.06.06.  This database includes data from the nightly science
processing (real-time analysis) of PS1 data from the 3pi survey only
(no MD, STS, etc data is currently included).  The data runs through
2012.06.01, and includes 2MASS and WISE photometry.  The database
includes proper motion and parallax fits for all objects where
appropriate (Trange > 400, delta parallax factor > 0.25, sufficient
measurements), but **no correction for the Koppenhoefer Effect**.  The
photometry is tied to the ubercal analysis table ucalqv_noref.fits.

Between this database and the previous 20120525 database, an error in
the relative astrometry caused a major problem with the SuperCOSMOS
data.  The SuperCOSMOS data had been ingested using a crude guess at
the plate solutions, a guess which was wrong in substantial ways.
The error had no impact (because the plate solutions were not used to
determine the SuperCOSMOS detection positions -- these were imported
from the reference) until the relative astrometry calibration was
performed.  The relative astrometry calibration accepted the incorrect
plate solutions and applied them to the SuperCOSMOS detections.  These
new positions were then used in the astrometry analysis, causing some
chaos.  

To repair the problems, the entire SuperCOSMOS dataset was deleted
from the database.  The astrometry of the non-SuperCOSMOS detection
data was not affected, and the mean positions were recalculated based
on the data without SuperCOSMOS.  The relative astrometry program has
since been modified to ignore the SuperCOSMOS data until a more
sensible solution can be devised.
