Trending plots for monitoring VIMOS astrometry.
The CCD-to-sky transformation converts pixel coordinates onto a virtual plane
which is free of instrument distortion. Coordinates of the virtual plane can
be transformed into celestial coordinates using the WCS. For QC purposes, the
inverse transformation is monitored by converting nine virtual data points
(Xsky, Ysky) = (512, 610), (1024, 610), (1536, 610), (512, 1220),
(1024, 1220), (1536, 1220), (512, 1830), (1024, 1830), (1536, 1830)
into CCD coordinates (Xccd, Yccd). Plot number 5 monitors the difference
between both, i.e. DeltaX0 = Xccd-Xsky or DeltaY0 = Yccd-Ysky, respectively,
for the central data point. For the other eight plots, the Delta X0 (or Delta Y0)
values have been subtracted: they show Xccd-Xsky-DeltaX0 or
Yccd-Ysky-DeltaY0. Therefore, the central plot shows the overall shift of
the transformation wherease the others show changes in the distortion.
Three astrometric fields are currently used: Region E, Region M, and Region N.
Pipeline recipe: vmskyccd.
General information
Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot.
If configured,
- data points belonging to the latest date are specially marked
- statistical averages are indicated by a solid line, and thresholds by broken lines
- outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
- "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
