From within the UltraDAS system (the console with the OBS> prompt), you can select different observing modes for INGRID. These save time, since the various INGRID wheels are moved simultaneously. Besides, the best imaging configuration is 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 INGRID observations North is up and East is left for PA=0° (check).
