J/ApJ/253/485  High-latitude HEAO 1 A-2 sources X-ray sample (Piccinotti+, 1982)

A complete X-ray sample of the high-latitude (|b|>20°) sky from HEAO 1 A-2: log N-log S and luminosity functions. Piccinotti G., Mushotzky R.F., Boldt E.A., Holt S.S., Marshall F.E., Serlemitsos P.J., Shafer R.A. <Astrophys. J., 253, 485-503 (1982)> =1982ApJ...253..485P (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, galaxy ; X-ray sources ; Redshifts Keywords: Galaxies, cluster of - luminosity function - X-ray sources Abstract: The HEAO 1 experiment A-2 has performed a complete X-ray survey of the 8.2sr of the sky at |b|>20° down to a limiting sensitivity of ∼3.1x10-11ergs/cm2/s in the 2-10keV band. Of the 85 detected sources (excluding the LMC and SMC sources), 17 have been identified with galactic objects, 61 have been identified with extragalactic objects, and 7 remain unidentified. The log N -log S relation for the nongalactic objects is well fitted by the Euclidean relationship. We have used the X-ray spectra of these objects to construct the log N-log S relation in physical units. The complete sample of identified sources has been used to construct X-ray luminosity functions, using the absolute maximum likelihood method, for clusters of galaxies and active galactic nuclei.

Note (1): No correction has been applied to confused sources to calculate whether each object individually would have fallen above the Piccinotti flux threshold Note (2): Morphological type: bagn : broadline AGN bllac: BL Lac object clus : Cluster of galaxies nagn : Narrowline agn Note (3): References for redshifts: ACO : Abell et al., 1989, Cat.

Note (4): Notes: 4: Two clusters at same z; IPC data give flux ratios of 2:1 5: Weak contribution from 0328-5244 cluster 6: Two sources in Piccinotti error box; Remillard (A3) ID used in table 7: Two clusters in same fov (A 3391, z= 0.0531) 8: M81 and M82 in FOV. Best fit position is consistent with M82 having most of the flux. 9: MKN 766 in FOV. Spectra indicates that 1215+30 has most of the flux. 10: NGC4696 also noted in Jahoda list 11: >2 clusters in FOV; Abell 3562 z=0.050 12: Many Abell clusters in field (e.g. A 3572). No IPC image. Piccinotti redshift for different cluster (SC 1345-301). 13: Possible confusion with A2063 (1521+083)and MKW3s(1519+0752) 14: Abell 3827 nearby; z=0.0993. ID based on richness and z, although both could be significant X-ray emitters. 15: A 2440 (z=0.0904) also in FOV. Einstein images and EXOSAT/GINGA spectra have shown that the cluster is softer and would not lie above Piccinotti limit. 16: S1101 (z=0.0564) also in FOV. Einstein images and EXOSAT/GINGA spectra have shown that the cluster is softer and would not lie above Piccinotti limit.
