These plots show information derived from arc observations with a
slit vs. the slit width.
The change in spectral resolution is caused by using a more suitable value for
one of
the arc recipe command line parameters since 2017-12. Details are given in the
history
section of the plot tutorial.
For more information see the
plot tutorial page.
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
