Special Remarks:
Special sequence of SCI-PRISM/SCI-GRISM/CAL-PRISM
Abstract for MTS:
MIDI observations of the massive young star MWC 349A. Since a calibration star bright enough for the grism mode is not available, a special execution sequence is approved by a waiver: Science target in prism mode , directly followed by the same science target in grism mode, followed by the calibrator in prism mode (calibrator in grism mode not used).
There are three such sequences on each of two baselines (here G0-H0).
Note that the target is at declination +40 deg, and thus never rises above 25 deg above horizon (approved by positive technical feasibility assessment). The LST ranges ensure that the target is at least 20 deg above horizon.
