== Reductions ==

|| Reduction || Date || Reference Catalog || Notes ||
|| SAS2.123.rerun20111129 || 2011-11-30 || Synth || Consistent re-reduction with synthetic catalog.||
|| czw.SASg.bkg || 2011-12-13 || Synth || Includes improved PATTERN.ROW/PATTERN.CELL choices. Only available in g filter.||
|| czw.SAS.continuity || 2012-02-29 || Synth || Includes continuity correction. ||
|| czw.SAStest || 2012-03-30 || PS1.REF.20120325 || Includes Noisemap correction. ||

== Key ==

Each plot shows the histogram of the previous reductions, indexed by the box width and the pattern used to fill the box.  The SAStest (which uses the new reference catalog) is consistently plotted in blue, whereas all previous reductions are plotted in a color representing the filter:
|| Color || Filter ||
|| Green || g.00000||
|| Red   || r.00000||
|| Purple|| i.00000||
|| Black || z.00000||
|| Brown || y.00000||
