Abstract for MTS:
AO-assisted spectrosacopy at 1090.4 nm of periodic variable star. 21 science OBs. 21 telluric calibrator OBs. Each science OB ("V393Sco-...") is to be followed immediately by a telluric calibrator OB ("CAL-telluric-...").
NOTE: during the first sereies of observations the telluric Hip087370 could not
always be used because of wind restrictions. Therefore, another alternative telluric,
Hip088159, is provided that only should be used if the Southern telluric cannot be
observed due to strong winds.
In addition, all OBs are time-critical: the user wants to have three sequences of one week each. In each week-long sequence, one science OB + one calibrator OB should be
executed each night. Each of the three sequences should be separated in time by two months. A similar sequence has been requested for UVES (run 081.D-0457(A)). The user is requesting that some of the UVES and CRIRES observations should be done during the same nights, but note that this is not possible for all sequences, nor is this a critical requirement, so please feel free to start a new CRIRES series even if it is not possible to get some data simultaneously with UVES.
Note added on 11.08.2008: User has requested that we do one epoch as soon as possible (even if this means not getting all data for the epoch), and the other epochs in P82.
Note added on 29.08.2008: User relaxed the time constraint in the sense that a
sequence of 4-5 completed OBs with some gaps of 1-2 days are acceptable, and such
a sequence can be regarded as successfully completed. The next sequence shouls be
taken in Sep 2008.
