Population RMS of all values contributing to the mean spectral resolution. The values trended here are for the 300V grism with a slit width of 1.0" and the order separation filters GG375 and GG435, respectively.
General information
Click on any of the plots to see a close-up version.
If applicable, the 20 latest values from Paranal ops logs are plotted as blue dots.
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
