Abstract:
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. (1985AJ.....90.1599P) VLBI survey and
contains all the sources in the declinations between -30 and +43
degrees 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.

Note (1): B1950 coordinates are taken from Preston et al. (1985AJ.....90.1599P)
and Morabito et al. (1986AJ.....91.1038M).
Note (2): Optical identifications (OI) andred shifts are taken from
Veron-Cetty & Veron (1998, Cat. ) or, if not found there,
are taken from the NASA/IPAC Extragalactic database (NED).
The abbreviations used are "Q" for quasars, "BL" for BL Lacertae
objects, "G" for galaxies, "RS" for radio sources. In the latter
case we do not have OI.
Note (3): Optical spectrum classification is taken from
Veron-Cetty & Veron (1998, Cat. ).
Note (4): Correlated flux density at 13 cm with errors are taken from
Preston et al. (1985AJ.....90.1599P).
