VizieR Online Data Catalog: Northern XMM-XXL field AGN catalog (Menzel+, 2016)
Abstract
The XMM-Newton XXL survey (XMM-XXL, PI Pierre) is a medium-depth (10ks per pointing) X-ray survey that covers a total area of 50deg2 split into two fields equal in size. In this paper, we focus on the equatorial sub-region of the XMM-XXL (XMM-XXL north), which overlaps with the SDSS-DR8 imaging survey (Aihara et al., 2011ApJS..193...29A). The XMM-XXL north observations were distributed around the area of the original 11deg2 XMM-LSS survey (Clerc et al., 2014MNRAS.444.2723C) and therefore build upon and extend that sample.
The X-ray data used in this paper are primarily from the XMM-XXL and XMM-LSS surveys. We also include however, any additional XMM-Newton pointings that are contiguous to the area covered by those programmes, such as the XMM-Newton observations of the Subaru/XMM-Newton Deep Survey (SXDS; Ueda et al., 2008, Cat. J/ApJS/179/124) (1 data file).- Publication:
