cds-question@unistra.frgalaxiesradio-sourcesx-ray-sourcesphotometryastrometryWe present catalogues of discrete, compact radio sources in and around the discs of 35 edge-on galaxies in the Continuum Halos in Nearby Galaxies - an EVLA Survey. The sources were extracted using the pybdsf program at both 1.6 GHz (L band) and 6.0 GHz (C band) from matching resolution (~=3 arcsec) data. We also present catalogues of X-ray sources from Chandra data sets for 27 of the galaxies. The sources at the two radio frequency bands were positionally cross- correlated with each other, and the result cross-correlated with the X-ray sources. All catalogues are included for download with this paper. We detect a total of 2507 sources at L band and 1413 sources at C band. 75 sources have been successfully cross-correlated in both radio bands plus X-ray. Three new nuclear sources are candidates for low luminosity active galactic nuclei in NGC 3877, NGC 4192, and NGC 5792; the one in NGC 3877 also appears to be variable. We also find new nuclear sources in two companion galaxies: NGC 4435 (companion to NGC 4438) and NGC 4298 (companion to NGC 4302). We have also discovered what appears to be a foreground double star; each star has X-ray emission and there is radio emission at both L band and C band in between them. This could be a colliding wind binary system. Suggestions for follow-up studies are offered.2022MNRAS.512.5755Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/512/5755CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/622/A4 : LOFAR observations XMM-LSS field (Hale+, 2019)J/MNRAS/460/2385 : Bootes field LOFAR 150-MHz observations (Williams+, 2016)J/ApJ/793/82 : LOFAR Bootes and 3C295 field sources (van Weeren+, 2014)J/AJ/150/81 : CHANG-ES.
