      This plot
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
