Major Instrument Modes: ISAAC SW MR spectroscopy

RA Range: 11-18

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 2.0 3THN 5.0 1.0 30


Pre-imaging run? No! Chilean run? No! Special calibrations? No!
Time critical? No! ToO? No! Carry-over run? No!


Special Remarks:


 
 
  High resolution spectroscopy of very bright stars. Huge overheads, the 
efficiency of the program is only 5%. However, given the nature of the 
targets it does not seem possible to find a way around. 

  Telluric standards are provided and supersede the calibration plan. Each
telluric standard (flagged in the name with TLSTD) indicates in the name the
program stars that it calibrates.

  Fewer telluric standards than objects provided, but some standards
intended to calibrate two science targets. In view of the already
extreme inefficiency of this program, please try to group objects in
sequences having the telluric standard in common: for example,
HD100564->TLSTD100546_104237...->HD104237. Given the relaxed constraints
and short execution time per OB, this should be feasible. 

  1-minute rule violated. Accepted, due to the nature of the sources to
be observed. Active optics is not needed for the execution of this
program, ONECAL at the beginning should do. 

  Finding charts provided, but probably not needed -all the targets are
bright or very bright.
