Trending plot for resolution (resolving power R) derived from MOS arc lamp measurements.
Only arc lamp measurements taken to calibrate MOS science observations are
used; exposures with the standard star masks are disregarded. Only
measurements with slit_width_dis=1.0 are plotted.
Resolution is measured at the blue and the red end, and at the centre of the
spectral range. The "cent" plots only show the latter; they include scoring.
The "full" plots also show the results at the blue and red ends; these are not
scored.
For LR_blue, the resolution at the blue and red ends is usually not
well determined; therefore only the central value is
plotted.
For MR, there is a similar issue at the blue end for masks with multiplexing:
spectra from slits which are at the same x position can overlap and
the pipeline then reports R=0 for the resolving power at the blue end.
Template ID: mos_cal_Arc (daytime), mos_cal_NightCalib (attached
night-time). Pipeline recipe: vmspcaldisp.

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
