In order to check table column values,
here is a sample of individual visit histograms:
Plot of NUV exposure vs. FUV exposure
for DIS and
Note NUV-only and FUV-only exposures,
as well as cases where the FUV exposure
is only a fraction of the NUV exposure.
The total number of sources in the catalog increases with exposure time: dis_2.ps .
The median delta-detector-Y is separation is larger than the X separation between matches: dis_6.ps .
The median major axis value (in arcseconds) is larger in NUV than FUV: dis_7.ps .
The median separation increases with decreasing exposure time: dis_11.ps (presumably due to
brighter sources having worse position accuracy).
The fill ratio (matched sources / total sources) increases with exposure time: dis_12.ps
(due to increases number of FUV sources with exposure time). Note the cluster of points where the FUV exposure time
was much smaller than the NUV exposure time.
The fill ratio increases with decreasing median separation: dis_13.ps .
Also the median separation increases for shorter exposures.
Note here that the average separation increases with a redder color: color_sep_exptime.ps . Color histogram: color_hist.ps .
These plots were generated from the statistics header cards
in the -mcat.fits files.
