General Description

• Simple imaging and coronography run. 
  
  The scientific targets are either within the allowed brightness
  regime or are prepared to be observed with the semi-transparent
  coronographic mask (priority 2 targets).  
  
  In case of possible saturation please adjust DIT and NDIT 
  according to the current weather conditions, keeping DIT * NDIT 
  always the same product as specified by the values in the OB, while 
  staying below the saturation limit and best (if possible) even below
  the linearity limit!!  
  
  Special case for HIP 10679 and HD 14082:
  These stars are quite close together (~7" in RA, ~12" in Dec), but
  too bright for regular observations. ND_Short is not good for the
  science observations here because we would like to find faint companions.
  Therefore we use a coronograph and rotate the field such that only
  one component is always in the field of view.
  Per OB we rotate four times and the star will loose its position behind
  the mask due to the rotation.
  Please (!) put ND_Short in after each rotation and adjust the 
  DIT to 6.5s, recenter the star under the lower left (!) mask and 
  put ND_Short out (!!) again. (Thank you)
  
  We need astrometric calibration observations using double stars. 
  The appropriate OBs are marked as CAL_... following the Service mode 
  Guidelines.  
  CAL_HIP... to calibrate the imaging observations (S13) 
  CAL_S27_HIP... to calibrate the coronographic observations (S27)  
  
  The astrometric calibrations should be done best in the nights of 
  observations (one each if several nights and if possible) or at 
  least close in time.  
  
  Please do never saturate, except in the case of Astrometric calibration, 
  where slight saturation, if unevitable, is okay! 
  Thank you.
