      The NASA Infrared Telescope Facility is a 3.0-meter telescope           
      located at the summit of Mauna Kea on the island of Hawai'i.

      The observatory location data given here are geodetic latitude and      
      east longitude, based on values from the Astronomical Almanac, 1989.    
      The geocentric site radius was determined using the MERIT 1983 earth    
      figure, equatorial radius = 6378.137 km and flattening of the reference 
      spheroid = 1/298.257.
