Survey of Instantaneous 1-22 GHz Spectra of 550 Compact Extragalactic Objects with Declinations from -30deg to +43deg
We present observational results for extragalactic radio sources with
milliarcsecond components, obtained with the 600 meter ring radio telescope
RATAN-600 from 1st to 22nd December, 1997. For each source, a six frequency
broad band radio spectrum was obtained by observing simultaneously with an
accuracy up to a minute at 1.4, 2.7, 3.9, 7.7, 13 and 31 cm. The observed list
is selected from Preston et al. (1985) VLBI survey and contains all the sources
in the declinations between -30deg and +43deg with a correlated flux density
exceeding 0.1 Jy at 13 cm. The sample includes the majority of sources to be
studied in the current VSOP survey and the future RadioAstron Space VLBI
mission.Comment: 26 pages, 4 figures, 5 tables, published in the A&AS; figure 4 with
the broad-band spectra plots is included in the preprint; tables 1 and 5, in
electronic form, as well as the ReadMe file can be extracted from the
preprint sourc
