Observing system

As part of the NOTCam calibration plan, we intend to provide NOTCam darks every night taken with all the exposure times and read modes used in a night. In order to do this automatically at the end of every night, a script called ``notcam.notcam-calibs'' was developed that takes 10 darks in each of the exposure times and modes used during a night. This script has been implemented, and information about how to use has been included in the NOTCam Cookbook.
