General Description

• Simple LSS to identify the nature of the optical counterpart of an ultra-luminous
   X-ray source (ULX) in the outer spiral arms of the galaxy MCG-3-34-63.
  
  
  ACQUISITION
  ===========
  
  Please centre on MCG-3-34-63 nucleus as best as is possible. The faint ULX should
   then lie on the slit at the position angle of 210.6 degs (ROT ANGLE=-210.6 = 149.4).
   The ULX is clearly seen on HST WFPC images, but will be too faint in the acq images.
  
  Exact nuclear magnitude of the host galaxy is not known, so please adjust exposure
   time during acquisition, if required.
  
  
  
  OBs
  ===
  
  Four identical simple OBs. The only modification is that in the first OB, the number
   of exposures are doubled and the integration time of each is about halved. This
   is just in case the unknown magntiude of the nucleus should be widly wrong. 
  
  
  
  
  FINDING CHARTS
  ==============
  
  079.D-0299A.001.jpg : Large scale (5x5 arcmin) DSS1 image.
  
  079.D-0299A.002.jpg : Zoom-in of the nucleus and ULX region. This is a WFPC2 image
   slightly smoothed to simulate realistic seeing. The image scaling shows the nucleus
   clearly.
  
  079.D-0299A.003.jpg : Same image as the previous one, but not smoothed. Image scaling
   is chosen to emphasize the ULX.

Waiver Requests

• We requested a change of phase 1 seeing constraint -- to improve it from
   1.0 arcsec to 0".8, in order to better subtract the background from the host galaxy.
   Waiver 079.D-0299A.01.WAV was approved.

Critical Observing Condition Constraints

• A good seeing will help us to better separate the ULX from the host galaxy.
