From within the UltraDAS system (the console with the OBS> prompt), you can select different observing modes for LIRIS. These save time, since the various LIRIS wheels are moved simultaneously. Besides, the best configurations for imaging, spectroscopy etc. are chosen automatically, thus significantly reducing the number of possible error sources during night time operation. An overview of the currently available, predefined modes is given below.
NOTE: For all LIRIS observations North is up and East is left for PA=0°.
