LIRIS Predefined Observing Modes

From within the UltraDAS system (the console with the SYS> 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&deg.

Spectroscopic mode:   lspec <option> <option: slit>

Argon and Xenon lines for grisms: lr_zj, lr_hk and mr_k.
Argon lines for grisms: lr_zj and lr_hk.
Xenon lines for grisms: lr_zj and lr_hk.

The slit wheel is not moved unless you give the name of the slit mask as an additional, second argument. Alternatively, the desired slit mask can be inserted separately with
lslit <slit mask name>
