A Radio Continuum Survey of the Galactic Plane at 10 GHz

Handa T. Sofue Y. Nakai N., Hirabayashi H., and Inoue M.

A 10.55 GHz radio continuum survey of the galactic plane in 356 < l < 56 |b| < 1.5 was made at the Nobeyama radio observatory using the 45-m telescope. The half power beam of the resultant map is 3.0' and the noise level of the resultantmap is typically 15 mK in Tb. Thirty-one contour maps and a list of 144 small diameter sources are presented.

The source NGC7027 was used as the primary calibrator for flux density, and was assumed to be 6.65 and 6.61 at 10.05 and at 10.55 GHz, resprectively based on the spectrum of Andrew et al., 1981, A&AS., 99, 36. The sources 3C348, 3C48, and 3C123 were used as the flux calibrators until June 1983. S(3C48) = 2.82 at 10.05 GHz based on the spectrum of Andrew et al., (1981). S(3C348)= 4.10 Jy/beam at 10.05 GHz. S(3C123)=7.94 Jy at 10.55 GHz based on the spectrum of Andrew et al., (1981).
