J/A+AS/52/63      H I Survey of the Galactic Center Region      (Burton+ 1983)

Description:
   Presented here are 21-cm observations of neutral hydrogen emission from the
   core of our Galaxy made over a period of several years with the 140-foot
   telescope of the National Radio Astronomy Observatory.  The survey covers
   the region 348 < l < 10, -10 < b < 10 with an angular resolution of 21' and
   a grid spacing of 0.5 degrees in both l and b, and the velocity range
   |v| < 310 km/s with a kinematic resolution of 5.5 km/s.  The sensitivity of
   the data generally corresponds to an antenna-temperature rms level of 0.02 K
   or better.
      
   The H I spectra from the survey are archived in a single three-dimensional
   (v, l, b) data cube in FITS image format.  There are 224 velocity channels
   with a step of 2.75 km/s between channels.  The intensities are given in
   units of antenna temperature and can be converted to brightness temperature
   units by multiplying by a factor of (1.52).
