VII/15      Galactic Supernova Remnants Catalogue (Ilovaisky+ 1972)
================================================================================
Galactic Supernova Remnants Catalogue
    Ilovaisky S.A., Lequeux J.
    <Astron. & Astrophys., 18, 169 (1972)>
    =1972A&A....18..169I
================================================================================
ADC_Keywords: Supernova remnants; Radio sources

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 10-26 W m-2 Hz-1) at 1 GHz, mean angular
   diameter of the source (arcmin), surface brightness at 1 GHz, 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 on flag:
  "*" if the source is not a supernova remnant (SNR) according to Clark and 
  Caswell list.

Note on S:
  1 flux unit = 10-26 W m-2 Hz-1
