We present GLADE+, an extended version of the GLADE galaxy catalogue introduced in our previous paper for multimessenger searches with advanced gravitational-wave detectors. GLADE+ combines data from six separate but not independent astronomical catalogues: the GWGC, 2MPZ, 2MASS XSC, HyperLEDA, and WISExSCOSPZ galaxy catalogues, and the SDSS-DR16Q quasar catalogue. To allow corrections of CMB-frame redshifts for peculiar motions, we calculated peculiar velocities along with their standard deviations of all galaxies having B-band magnitude data within redshift z=0.05 using the “Bayesian Origin Reconstruction from Galaxies” formalism. GLADE+ is complete up to luminosity distance dL=47+42 Mpc in terms of the cumulative B-band luminosity of galaxies, and contains all of the brightest galaxies giving half of the total B-band luminosity up to dL250 Mpc. We include estimations of stellar masses and individual binary neutron star merger rates for galaxies with W1 magnitudes in GLADE+. These parameters can help in ranking galaxies in a given gravitational wave localization volume in terms of their likelihood of being hosts, thereby possibly reducing the number of pointings and total integration time needed to find the electromagnetic counterpart.
