Description:
This extensive survey of the first quadrant of the Galaxy (GLON from
20 to 60 degrees, GLAT from -1 to +1 degrees) was taken with the 60-cm
submillimiter-wave telescope of the University of Tokyo-Nobeyama Radio
Observatory. The HPBW (half-power beam width) is 9±1 arcmin at
230GHz, and the intensity scale of the data is stable within typical
fluctuations of 5%. It was carried out between December 1992 and
May 1993.
The survey gives the main-beam brightness temperatures (sensitivity
of 0.4K) on a grid spaced every 15' (0.25 deg) in GLON and GLAT,
and velocities spaced every 0.65km/s between -13 and 153 km/s
(velocity resolution of 0.3km/s)
