Estimated Total Execution Time (hours, including overheads)

• 9h59m55s

General Description

• This project obtains UBVRI photometry of young stars for a multi-colour
   study of their 
  properties. Most sources - very low mass stars and brown dwarfs - are very red and
   rather 
  faint, and therefore need long integrations in UBV for reasonably precise photometry.
  Some brigther targets are observed with shorter exposures in order not to saturate
   them.
  
  We require standard calibration. In addition to the photometric calibration according
   to the
  calibration plan, we provide calibration OBs to acheive a higher accuracy.

Waiver Requests

• Waiver Request 075.C-0335A.01.WAV granted
  to have OB execution times of more than one hour for ChaI-* object fields.
  
  Observing sequence has been arranged that redder filters are the last, 
  and seeing requirements have been relaxed to 1.2 arcsec up from <=1.0 arcsec
   
  requested in the proposal.

Special Calibration Information

• Two calibration OBs per object OB/field have been prepared. One of them
   should be executed immediatedly preceeding or following the execution of the object
   OB. 
  The two calibration OBs (called CAL-ChaI-*1/2) are at lower/higher RA than the object
   positions, so one of them will always be executible.
  
  We would prefer CAL-ChaI-*1 if no other important restrictions apply, since this
   field 
  contains more Landolt stars than then CAL-ChaI-*2.
