Calibration

A suite of flatfield and arc-lamp (CuHeAr Hollow Cathode) calibrations should be obtained every afternoon with the help of the Support Scientist. Night-time, per-field arc-lamp exposures can be obtained through the instrument control software with an overhead of approximately 2 minutes. Telluric calibration stars (A0V or G2V) can be chosen from IRTF webpage.
