The software for each instrument has internal checks to make sure lamps are not on when they should not, but it does not check if there is an other lamp on in a different instrument. To avoid such problems, a system wide command was made that checks the status of all the FIES/ALFOSC/NOTCAM lamps, and provides a WARNING if any one lamp is on. This script is executed in all the instrument set-up scripts that are normally run when switching from one instrument to an other.
Further work was made towards the implementation of the new FITS keywords that will carry information needed to link individual images to there corresponding observing blocks. A facility to automatically determine the observing mode in use, based on the setup-of the instrument was made.
