Trending plots for WCS shift from standard star observations.
QC parameters are derived from each of 32 detectors of OmegaCAM STD
frames. Data in all filters, excluding composite filter u_g_r_i_SDSS,
are combined in this plot.
DB Name: omegacam_std
Fits header: QC.DELTAX.SHIFT / QC.DELTAY_SHIFT
QC1 DB: qc_deltax_shift / qc_deltay_shift
Description:
The WCS shift in the STD observations measured in X and
Y-direction [pix].
These Health Check plots describe:
Fig. 1
shift_x: The WCS shift in X direction averaged over all 32
detectors [pix].
Fig. 2 shift_y: The WCS shift in Y direction averaged over all 32
detectors [pix].

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
