Instrument 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 or from the Gemini Observatory NIR Telluric Standards webpage.

Details on day-time calibrations are in the observing guide.
