X-ray Point Source Catalog of Sept 1994: 49,721 X-ray sources.
Fourth UHURU X-ray Catalog,
1979: 339 entries.
1400 MHz Abell Galaxy Cluster Survey:
About 440 galaxy clusters from 957 observed sources (1.4 GHz) between dec +83.1 degrees and -19.1 degrees.
Catalog of 5 GHz Galactic Plane Sources:
915 5 GHz sources found the galactic plane with a peak beam brightness temperature of at least 0.2 K (Kelvin) above the background, except in confused regions; an 0.2 K point source corresponds to 0.26 Jy. Covers the galactic planar region (galactic latitude range -2 b 2) extending from galactic longitude l =190 (northern Orion) through l = 0 (the galactic center in Sagittarius) to l = 40 (Aquila). Contains a few scattered sources from Orion to l = 2804 (Vela).
1987 Green Bank 300-foot 4.85 GHz Radio Survey:
54,579 discrete sources with angular sizes less than 10.5 arcmin and flux densities larger than S 25-40 mJy beteen -0 degrees and +75 degrees dec.
Molonglo 408 MHz Source Reference Catalog, of 2 May 1990:
12,141 sources with each discrete source having a flux density of 0.7 Jy or greater.
Parkes 1990 Southern Source Catalog:
8,264 sources covering essentially all the sky south of dec +27 degrees but largely excludes the Galactic plane and the Magellanic Cloud regions. Flux measurements cover the frequency range 80 to 22,000 MHz but coverage at the highest frequencies is sparse.>
NRAO Faint Images of the Radio Sky at Twenty-cm ("FIRST") Preliminary Survey: 26,892 sources.
Parkes-MIT-NRAO (PMN) 4850 MHz Radio Surveys;
1994: 13,363 sources in the Tropical survey between -29 degrees and -9.5 degrees dec and 23,277 sources in the Southern survey between -87.5 degrees and -37 degrees. Flux limit which varies as a function of dec from 20 mJy at the southern survey limit to about 50 mJy at the northern limit.[pmn.me0
Fourth Cambridge Radio Survey Catalog, 1967:
4,844 sources between dec -7 degrees and +80 degrees at at 178 MHz.
Sixth Cambridge Radio Survey of Selected Areas:
24,209 sources at a frequency of 151.5 MHz covering a portion of the northern sky centered on dec of +41 degrees, +58 degrees, +75 degrees and +90 degrees. All survey sources are contained in a large contiguous region which extends in dec from +90 degrees to +30 degrees.
Catalog of Extragalactic Radio Source Identifications:
14,585 entry compilation of all published optical identifications of extragalactic sources, ``complete'' for relevant papers published through the end of 1983.
1400 MHz Northern Sky Catalog, Dec 1991:
31,524 discrete sources at 1400 MHz (1.4 Ghz or 20cm). The sources range in strength from 80 to 61100 mJy (milli-Janskys), and cover a dec from -6.3 degrees to +83.3 degrees (equinox 2000).
4850 MHz Northern Sky Survey, Sep 1990:
53,522 discrete sources at 4850 MHz (4.85 GHz or 6cm) ranging in strength from 13 to 59740 mJy (milli-Janskys), and covering a dec range of from -3.3 degrees to +75.9 degrees (equinox 2000).
