Plan for Science Observations in Winter 2000

• First SPARO science: Polarimetry of NGC 6334-I, with calibration to be made on 20 km/s cloud.

  
  Coordinates of the center of the 20 km/s cloud (a.k.a. M-0.13-0.08)
  are estimated from the map in Lis et al. 1994, also reproduced in
  Novak et al. 2000, and shown there with CSO 350 micron polarimetry 
  vectors superposed.
  
  They are (-5' 09" in dec and -2.6 s of R.A.) relative to Sgr A*.
  
  Using the J2000 Sgr A* coordinates of Rogers et al. 1994 (ApJ), 
  we get the following:
  
  J2000 coords of 20 km/s cloud center:
  17 h 45 m 37.4 s
  -29 d 05 ' 37 "
  

  For NGC 6334-I, want pixel 5 pointed at Az-averaged SPO for NGC 6334-I. And want chop of 0.5 degree. For 20 km/s cloud, will need to use Sgr B2 as a pointing reference, and will need to use a small chop (about 0.1 deg) to be compatible with CSO.
  
  Go to "update" to see current status of NGC 6334 polarimetry analysis. For this analysis, i.p. was determined using the Moon observations.
  
  
• Key science goal: Mapping field in Galactic Center
  
  The pointing postions for polarimetry are given in Greg's map of "fields"
  
  The main pointing reference for these observations is Sgr B2

  The center coords for science observations of Galactic center:
  
  Coordinates of Sgr A* are given by Rogers et al. 1994 ApJ as:
  
  J2000:
  17 h 45 m 40.0 s
  -29 d 00 ' 28 "
  

• other SPARO science for winter 2000:
  • more on bright Galactic clouds
  • R-CrA
  • cirrus clouds
