A suite of flatfield and arc-lamp (CeHeAr) calibrations will be acquired each afternoon by the instrument's Support Scientist. For night-time operation, per-field arc-lamp exposures (if needed) can be obtained through the instrument control software with a total exposure overhead of 2-minutes (for lamp-on, lamp-off exposures). Suitablely good telluric calibrator stars (A0V or G2V objects) can be chosen from this list.
