General Description

• This is a prgram to obtain HK spectra of canidate cluster members to measure
   the strength of  CO bandhead absorption in order to determine whether they are RSGs
   or not. Very 
  low resolution K band spectra already indicate that CO band head absorption is present
   but blending prevents the accurate measurement of it's strength, and hence a luminosity
   classification. Therefore, even a few (2-3) spectra would be invaluable 
  in  callibrating the lower resolution data. Finally, all sources are very bright
   and so the project may be attempted in relatively poor conditions.
  
  For a number of OBs I have been able to place two target stars in each slit - in
   each case I have specified in the OB which of the 2 targets in the slit the co-ordinates
   correspond to and also the distance in arcsec between the two stars - in no cases
   does this match the values selected for the nod throw (60 arcsec) - I hope that
   this will keep both stars in the slit at all times.  
  
  
  Note that I was advised to set combined offset=true for these OBs - I hope I have
   done this correctly!

Critical Observing Condition Constraints

• None

Time-Critical Aspects

• Given the highly competitive nature of this field, we would welcome any
   data ASAP - even if only one spectrum  such that we may use it to callibrate existing
   data.
