SOFI Calibration Plan: Arcs

Arcs Spectra are taken with the template SOFI_spec_cal_Arcs.

Load the template SOFI_spec_cal_Arcs from /data/SOFI/SYSTEM/COMMON/OBD into Bob and run it. The calibration unit will be automatically moved in and the internal calibration lamps automatically switched on and off when necessary.

In the default mode a full Arcs calibration is taken for the 1 arcsec slit, including the low resolution Red and Blue grisms and the high resolution grism with the Z, J, H and Ks filters. It takes about 15 minutes to run the template with the default values of the parameters.

The calibration unit will be put out at the end of the template.
