II/56 100-Micron Survey of the Galactic Plane (Hoffmann+ 1971)
================================================================================
The 100-Micron Survey of the Galactic Plane
Hoffmann W.F., Frederick C.L., Emery R.J.
<Astrophys. J. 170, L89 (1971)>

ADC_Keywords: Photometry, infrared; Surveys; Galactic plane; Infrared sources
Description:
The catalog represents a survey of a portion of the galactic plane
at a wavelength of 100 micrometers with a balloon-borne, stabilized,
12-inch infrared telescope having a sensitivity of 10(-22)
W/m2/Hz. The survey covers 750 square degrees of the sky,
including most of the galactic plane between galactic longitudes of
335 and 88 degrees, plus a number of other selected areas of
interest. Seventy-two sources have been detected, 60 of which are
identified with continuum radio sources, bright nebulae, dark
nebulae, and infrared stars. The catalog includes right ascension
and declination (B1950.0), galactic coordinates, 100-micrometer peak
flux densities, sizes of sources, and identifications.

Note on Sigma:
This is the ratio of the correlation of the signal with a function
representing the beam profile to the rms noise level of the
correlation.
Note on size:
Value of source size is given when the signal-to-noise is sufficient to
clearly distinguish the shape of the signal from that of a point source.
Note on Ident:
R - Radio Continuum
I - Radio Combination Lines
M - Molecular Lines
B - Bright Nebulae
D - Dark Nebulae
L - Radio Recombination Lines
