Trending plot for rms of dispersion solution 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.
For HR grisms, the rms of the dispersion solution should be < 0.6 pixels.
Higher values can indicate problems with mask insertion or with missing arc
lamp lines. For the MR grism, the rms is usually below 1.1 pixel. Higher values
can, however, be caused by multiplexing of the slits in the MOS masks (MR
only). If the
rms is 0 then this could indicate a pipeline failure caused by missing arc
lamp lines.
Template ID: mos_cal_Arc (daytime), mos_cal_NightCalib (attached
night-time). Pipeline recipe: vmspcaldisp.
Pipeline results for LR grisms are usually unreliable. They can be accessed here:
MOS disp LR_blue
and MOS disp LR_red.
General information
Click on any of the plots to see a close-up version.
If applicable, the latest values from Paranal ops logs are plotted as blue dots. More information about those values, including a download option, is available in the OPS column.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- 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
