Parameters for "wavecal"
The purpose of this task is to
derive a generic wavelength calibration for the night.
There are only two parameters to set:
All wavecal needs is the parameter "star" specifying
a bright object to trace an aperture
and the parameter "lamp" specifying a comparison lamp
to extract and identify.
You will be presented with the extracted lamp.
You don't need to start marking lines.
Just type one of the following:
to retrieve a previous solution and the lines will be marked automatically.
Then type "a" (to set the all option: VERY IMPORTANT) and "c" (to
Then you must type "f" (fit) and proceed as usual, deleting
lines with larger residuals, etc.
When satisfied with the fit, hit "q".
