Abstract:
We present radio continuum spectra for 200 Galactic supernova remnants
(SNRs) from 220 known and included in Green's (1998, Cat. VII/211)
catalog. The spectra can be plotted only for 200 SNRs because about 20
remaining new and weak SNRs (Whiteoak and Green, 1996, Cat.
J/A+AS/118/329; Gray, 1994MNRAS.270..847G 1994MNRAS.270..847G) have only one-frequency
flux density measurements. Spectrum plotting is an "on-line" procedure
of the CATS database (Verkhodanov et al., 1997ASPCo.125..322V 1997ASPCo.125..322V) created
for some other multi-frequency catalogs. These spectra include most of
the measurements available in literature, as well as multi-frequency
measurements of nearly 120 SNRs with the RATAN-600 radio telescope in
1, 2 and 4 Galactic quadrants and from the Galactic plane survey at
960 and 3900MHz (Trushkin, 1986ATsir1453....4T 1986ATsir1453....4T, 1987AISAO..25...84T 1987AISAO..25...84T,
1989, Ph.D. Thesis. SAO, Nizhnij Arkhyz, 1996BSAO...41...64T 1996BSAO...41...64T,
1998BSAO...46...62T 1998BSAO...46...62T). The measurements have been placed on the same
absolute flux density scale of Baars (1977A&A....61...99B 1977A&A....61...99B) as in the
paper by Kassim (1989ApJ...347..915K 1989ApJ...347..915K), using the correcting factor
from the compiled catalog (Kuhr et al., 1981, Cat. VIII/5). The
presented compilation has given a possibility of plotting quite
accurate spectra with the thermal plasma free-free absorption in
fitting the spectra accounted for.
