 Single target project aimed at measuring the radial velocity of the 
companion star of the low-mass X-ray binary 4U 1822-37. It requires 
dark time and nearly 6 hours to be taken continuously, in order to map 
the orbital period. It consists of five OBs of approx. 1h each (to be 
executed one after the other), for which the constraints must be 
respected. 

 The user has been warned that we will not repeat the entire sequence, 
if the atmospheric conditions degrade during these 6 hours. Should this 
happen, please interrupt the observing sequence and make a comment for 
USG in the night report. PI will be contacted and he will then provide 
time frames for the remaining OBs. 
 
  Please ignore statement on slit orientation in finding chart:
irrelevant as ELEV mode is to be used.
