The DEIMOS Slitmask Calibration Widget provides a simple means to acquire calibration data (arcs and internal quartz flats) for a series of slitmasks, allowing you to get dinner, sleep, etc., while it carries out your calibrations. Follow these instructions to use it:

1. Launch the tool from the DEIMOS Workspace Menu by selecting DEIMOS Utilities > Slitmask Calibration Tool.
2. Configure the spectrograph for taking calibrations:
   • Close the hatch.
   • Extinguish lamps.
   • Set grating and central wavelength as desired.
3. Under ARCS, set the number of arc exposures to acquire, the exposure time, and the desired lamps to use.
4. Under FLATS, set the number of internal quartz flats to acquire and the desired exposure time.
5. Under SLITMASKS, click on the names of all masks to be calibrated with this configuration.
6. Under OPTIONS, select Wait for FCS updates between exposures to have the script pause in between each slitmask to allow FCS to update 2 times and presumably recenter. If this is selected, FCSTRACK must be running or the script will hang.
7. Under OPTIONS, select Do end-of-night shutdown when done to have the script shutdown the instrument software after the calibration exposures are completed. This allows you to go to sleep at the end of the night while the script completes your calibrations.
8. Click GO to start acquiring data with the calib script.
