Description:
A survey of atomic hydrogen 21-cm line emission in the Galactic plane,
covering the region 12 deg > l > 245 deg and |b| < 10 degrees. The
survey was performed in 1981 using the Parkes 64-m telescope and sky
sampling intervals of 0.5 degrees in galactic longitude and 1 degree
in galactic latitude. The observed range in V(LSR) is between ±211 km/s,
with a velocity resolution of 0.824 km/s. The rms noise of the
observations is quoted as ∼1 K, and effects of stray radiation on the
observations are stated to be smaller than errors in the temperature
scale calibration.
This survey was designed to supplement the northern hemisphere HI survey
of Weaver and Williams (1973). Taken together, the two surveys
provided complete (though undersampled) 21-cm observations of the sky
within ± 10 deg of the Galactic plane. Note, however, that a later survey
by Kerr et al. (1986) provided a fully-sampled southern dataset with higher
sensitivity than that of Strong et al.
The survey data are archived as a single FITS file. The FITS image is stored
as a data cube, with LSR velocity on the first axis, galactic latitude on
the second axis, and galactic longitude as the third. The 21-cm line
intensity is quoted as a brightness temperature.
