Special Remarks:
Only *_H2S2 OBs are time-critical!
Abstract for MTS:
HR/HRX spectroscopy of Herbig Ae/Be systems in the H2 0-0 S(2) (12.28 microns) and S(1) (17.03 microns) lines. For each science target there are two OBs, one for the S(2) line (*_H2S2) and one for the S(1) line (*_H2S1). Both can be executed independently of each other. Finishing the observations of both lines on one target has priority over starting a new source.
The _H2S1 (17.03 micron) spectroscopy can be done on any date that the target is
observable; the _H2S2 line (12.27 micron) is located close to a telluric water
absorption band. To introduce a sufficient velocity shift (due to the reflex motion of the earth around the sun) to shift the line in the target outside of this telluric absorption line, these OBs can only be done in certain months, which are detailed in the README.
The user has supplied one telluric standard for each science *_H2S1 (17.03) OB, to be observed immediately following/preceding the science observation. Two telluric standards are provided for each _H2S2 (12.27 micron) OB, of which one (labelled _P) is to be executed immediately preceding the science observations, and of which the other (lablles _F) is to be observed immediately following the science OB.
A waiver has been granted to this programme to allow OB duration > 1 hour, with the usual caveat that OBs will not be aborted or repeated if conditions degrade beyond those specified beyond the 1 hour mark.
