... 88, Jan. 1983, p. 1-15. l. A survey of extragalactic radio sources made using driven declination scans is reported covering an area of about 0.07 sr to a limiting flux density of 35 mJy. The fast-scan survey was carried out at a galactic latitude greater than 17 deg with the NRAO 91-m telescope operating at 4.755 GHz, and the 480 sources detected were reobserved at 1.4 GHz with the National Astronomy and Ionosphere Center 305-m telescope at Arecibo. ...

This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

... The VSOP Survey Continuum Source List . The radio sample for the VSOP continuum survey was defined to include all extragalactic radio sources with: . a total flux density at 5 GHz, S>=1.0 Jy . ... The sample also included all sources in the sky with a 5 GHz flux density S>5 Jy, regardless of spectral index and galactic latitude. ... The source would then be included in the VSOP sample (three of the sources were found with a flux density above 1 Jy and added to the sample). ...

... During the analysis of the surveys carried out on RATAN-600, it was found that almost one fifth of the detected sources shows significant radio flux variations. ... We used the data from "Cold" radio surveys carried out with RATAN-600 in 1980-1994 to search for radio sources with significant flux variability. ...

... In order to produce the merged source-list from all the individual input source-list files, omsrclistcomb first produces a list of all the input sources sorted into order of decreasing source significance. To decrease the CPU time taken in the matching process, the distance (d) between two sources is computed from their equatorial-rectangulr coordinates (x, y and z), using the following formulae: . The equatorial coordinates are only computed once. ...

... We present the first results of an extensive near infrared survey of galactic and OH masers in high--luminosity star forming regions (SFR) aimed to see if there are near--infrared (NIR) sources directly associated with the masers. ... Although not in all sources there are high sensitivity--high resolution radio continuum observations, only few of the K--band/maser sources are closely associated with known ultracompact (UC) Hii regions. ...
