Taking Lamps with Lucifer
After your take some spectra, you may want to take arcs and lamp flats.
1. Put in the Calibration Unit.
2. Tell the operator to turn off WFS and guiding.
If you have WFS corrections on, you will put a lot of coma, etc into the telescope, and you'll be very sorry.
3a. Method #1: Run a script to do arc lamps and flat lamps. Examples are attached.
3b. Method #2: Take the Arcs Manually
Under the Calibration Unit gui, type OPEN GUI
do the exposure manually as before
Must turn off the arcs manually.
Use Halo2 for H&K flats.
* NB: The AZ observers decided that the night sky lines give good wavelength calibration for most projects, and so are no longer taking arc exposures during the night.
