cds-question@unistra.frradio-sourcesspectroscopyA multifrequency deep survey of a band of sky with the declination of the source SS 433 ({delta}~5{deg}+/-20') was performed as part of the "Kholod" program on the RATAN-600 in 1987-1988. The right ascension intervals covered by the survey are 0h<{alpha}<14h and 18h<{alpha}<24h. The spectral properties of 400 sources from the RC catalog were determined for the first time by using only RATAN-600 data. The maximum in the flux density distribution for these sources at the central wavelength, {lambda}7.6cm, occurs at ~30mJy. The lower flux limits for the sample at wavelengths of 3.9, 7.6, 13.0, and 31.0cm are 16, 9, 37, and 61mJy, respectively. These observations provide the first flux estimates at 13.0 and 31.0cm for 90% of the sources. Spectra were measured for the first time for 112 sources (28%) and were revised for 90 sources (23%). The maximum in the spectral index distribution for the entire sample in the interval from {lambda}{lambda}7.6-31.0cm occurs at {alpha}=-0.86+/-0.04 (S_v_~{nu}^{alpha}^). The spectra of some 20 of the sample sources (5%) are peaked at roughly 1GHz, and about 40 spectra (10%) have low-frequency breaks. Roughly 70 sources (19%) have flat spectra ({alpha}>-0.5), and 64 (18%) have very steep spectra ({alpha}<-1.1).1997AZh....74...42Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/74/42CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/33 : Spectral characteristics of RATAN (RC) Catalog (Bursov+ 1989)J/A+AS/87/1 : RATAN-600 7.6 cm radio sources catalog (Parijskij+ 1991)J/other/BSAO/40.128 : RATAN-600 radio sources spectra (Bursov 1996)J/other/BSAO/40.5 : RATAN-600 RC radio sources (Parijskij+ 1996)J/A+A/370/78 : RATAN-600 NCP bright radio sources (Mingaliev+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/74/42https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/74/42http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/74/42https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/74/42https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/74/42http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/74/42GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/74/42/table3 (Flux densities for RC radio sources (1988.0))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/74/42/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/74/42/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/74/42/table3?GETtext/xml+votable180.050000true2.32817214.96601180.0055555555555555565/5893 6/21 23 25 27 28 38 42 44 4116 4118 4121 4123 4134 4137 4138 4224 12309 12310 12311 12315 12316 12325 12326 12329 12330 12336 12352 17877 17881 17882 17883 17884 17895 17897 17898 17904 18133 18134 18135 18138 18140 18149 18150 18151 18154 18155 18156 18160 18197 18198 18202 18203 18213 18215 18217 18218 18220 18224 18240 18304 18902 18905 18907 18922 18923 18928 19157 19164 19174 19175 19177 19178 19180 19221 19223 19225 19228 19238 19239 19243 19244 19264 19478 19481 19484 19493 19495 19499 19500 19520 21887 21972 21973 21977 21978 21979 21989 21990 21993 21994 21996 22000 22207 22229 22233 22234 22246 22247 22250 22251 22256 22292 22293 22294 22298 22299 22300 22308 22309 22310 22313 22314 22315 22316 22400 22997 22998 23001 23002 23003 23004 23014 23017 23019 23257 23258 23259 23269 23270 23274 23275 23276 23317 23318 23319 23321 23323 23333 23334 23335 23360 23579 23590 23593 23595 23616 26070 26073 26075 26086 26090 26091 26325 26326 26329 26330 26332 26340 26342 26389 26390 26393 26394 26403 26405 26406 26407 26409 26410 26416 27093 27095 27097 27100 27109 27110 27113 27114 27115 27116 27349 27353 27354 27355 27365 27366 27369 27371 27372 27376 27413 27414 27417 27418 27420 27430 27433 27435 27456 27669 27670 27684 27685 27686 27688 27689 27690 27692 27712 30165 30166 30171 30182 30188 30192 30485 30486 30489 30491 30502 30503 30512 30528 31210 31211 31445 31510 31511 31513 31515 31525 31529 31530 31532 31536 31766 317716.361026645315661e-25 4.638248699215607e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/74/42?format=asciiOpticalRadiodefaultJ/AZh/74/42/table3Flux densities for RC radio sources (1988.0)recnoRecord number assigned by the VizieR team.
