ADC_Keywords: Radio sources
Description:
A sample of 112 sources with flux densities higher than 200mJy at the
4.85GHz and with the range of declinations from +3 till +5 degrees
from the Green Bank survey catalog 87GB was observed at
three frequencies: 0.96, 3.95, and 11.1GHz. The observations were
performed in January and February 1992, in the Northern sector of the
RATAN-600 radio telescope. The accuracy of the source right ascensions
was improved by a factor of 5-10 (for 70% of the sources the accuracy
of the right ascension is 0.1arcsec). About 80% of the objects studied
were identified with sources from the Texas survey.

--------------------------------------------------------------------------------
Note on Rem:
# = The spectral indices were determined from flux densities at 7.6 and 31cm
(in the absence of identification with the Texas survey)
* = the source is from the Sternberg Astronomical Institute survey list
** = the source is identified with the adjacent lobe
*** = the source signal was not distinguished because of interference from a
nearby background source. The flux densities at 6.2 and 82cm from
the Green Bank and Texas surveys.
ref = a reference object
