Description:
Radio-frequency absorption line observations of 20 sources were used
to calibrate the relation between radio surface brightness and linear
diameter. Distances for 116 SNR were derived using the new
calibration. The catalog lists galactic longitude and latitude in
decimal degrees, source name, flux density (in 10-26W/m2/Hz) at
1GHz, mean angular diameter of the source (arcmin), surface brightness
at 1GHz, diameter of the remnant (pc), distance of the remnant (kpc),
scale height from the galactic plane (pc), radial distance to the
center (kpc), and references (by number given in the original
publication).

Note (1): Flag as follows:
* = if the source is not a supernova remnant (SNR) according to Clark
and Caswell list.
Note (2): 1 flux unit = 10-26W/m2/Hz = 1Jy
