Abstract for MTS:
High-resolution spectroscopy at 12.405, 12,454, 12.829 and 12.893 microns of water-lines in YSO disks. Two science targets, 12 science OBs. Targets should be the brightest mid-IR source within the VISIR field-of-view. For each science OB, there is an associated calibrator OB ("Calib....."), which is to be executed immediately before or after the science OB.
Since this programme wants to measure water in space, it would benefit from being done under conditions of relativelly low humidity. So please only do this programme when the PWV contents is relatively low.
A waiver has been granted to this programme to use a free wavelength setting (12.893 microns), under the condition that this will be done on a best effort basis only, with the user bearing all the risks. A waiver has also been granted to this programme to allow OB duration longer than 1 hour, with the usual caveat that OBs will not be aborted or repeated if conditions degrade beyond those requested after the 1 hour mark.
Note added on 21.08.2009: During the first attempt to ececute OB #379082 ("Calib RNO90 12.829 part 2"), sky lines were saturated (background level above 3000 ADUs). This OB and the corresponding science OB has to be re-queued. Therefore: please inspect all obtained data for this programme carefully, and adjust the weather flag to "P" or "F" if there is risk of saturation!
