Study of RCR Catalogue Radio Source Integral Spectra
  We present the characteristics of the sources found on the averaged scans of
the "Cold" experiment 1980--1999 surveys in the right-ascension interval $2^h$<
RA <$7^h$. Thereby, a refinement of the parameters of the RC catalog sources
(RATAN Cold) for this interval is complete. To date, the RCR catalog (RATAN
Cold Refined) covers the right-ascension interval $2^h$< RA <$17^h$ and
includes 830 sources. The spectra are built for them with the use of new data
in the range of 70--230 MHz. The dependence between the spectral indices
$\alpha_{0.5}$, $\alpha_{3.94}$ and integral flux density at the frequencies of
74 and 150 MHz, at 1.4, 3.94 and 4.85 GHz is discussed. We found that at 150
MHz in most sources the spectral index $\alpha_{0.5}$ gets steeper with
increasing flux density. In general, the sources with flat spectra are weaker
in terms of flux density than the sources with steep spectra, which especially
differs at 150 MHz. We believe that this is due to the brightness of their
extended components, which can be determined by the type of accretion and the
neighborhood of the source.
