Special Remarks:
A calibration OB has to be taken after each science OB
Abstract for MTS:
K-band spectroscopy of massive accretion disks around 4 young stars with AO.
2 stars are observed with 6 OBs each, 1 star with 3 OBs and the remaining with 1 OB. Each OB contains two wavelength settings.
Each science OB has a corresponding calibration OB (CAL_*) as described in the user comments of each OB. This has to be observed right after the science OB. The telluric
HR4731 has two finding charts. Also the SCI_IRAS18151 have two finfing charts. The
second one is from a SV snapshot and shows the AO guide star!
The user asks for fewer CAL OBs if the science OBs are taken in a row: "if the science OBs will be executed many in a row within a single night, we prefer to do the calibration only every 2-3 hours and spent correspondingly more time on the targets. Depending on weather and seeing conditions, these descision can please be taken by the operator."
Vignetting problem: some vignetting on detector 1 acceptable since the science can
also be done on detectors 2 and 3.
