CRIRES-POP Observing Information

General strategy

The CRIRES-POP targets were bright objects which could be observed also under moderate weather conditions. The concept was, thus, to have a filler programme which uses time with insufficient seeing conditions for other programmes. The approximately 200 wavelength settings per target were split into observing blocks of 20 minutes to 1 hour in length. These blocks were not observed in a continuous way. In fact, some of the spectra from 1 to 5 mu have been obtained over a time span of almost 1.5 years.
