Notes. Columns are (1) name of the source, (2) right ascension (h:m:s), (3) declination (d:m:s), (4) redshift, (5) galactic hydrogen column density, NH, in units of 1022 atoms cm−2 obtained from Willingale et al. (2013), (6) type of the source, (7) observation ID (ObsID), (8) epoch, (9) date of observation, and (10) exposure time in sec. Some of the information, including the right ascension, declination, and z, are from Véron-Cetty & Véron (2010). The ObsIDs that are analysed for the first time are shown in bold.
