Abstract:
We are introducing a value-added full-sky galaxy catalog with high
completeness for identifying gravitational wave (GW) sources in order
to support future electromagnetic (EM) follow-up projects of the
LIGO/Virgo Collaboration. The catalog GLADE (Galaxy List for the
Advanced Detector Era) has been constructed (combined and matched)
from four existing galaxy catalogs: GWGC, 2MPZ, 2MASS XSC and
HyperLEDA. It contains 1918147 galaxies, which is two orders of
magnitude greater than the number of galaxies in the GWGC catalog
alone (53312), which is currently in use by the collaboration.
Furthermore we considered it as a crucial requirement towards the
catalog to contain B-band magnitudes and distances for all entries.
Therefore we have associated these properties for 548876 2MASS
galaxies which lacked them with a regression algorithm teached on a
subsample of the 2MPZ catalog. Our catalog is complete to 73Mpc and
even at 300Mpc has a relatively high completeness (53%). Naturally,
our catalog could be used in a broad range of various astrophysical
projects besides EM follow-up efforts.We are introducing a value-added

Note (1): Cosmological parameters used to calculate distance from redshift:
H0=70, Omegam=0.3, OmegaLambda=0.7
Note (2): For error on Bmag2MPZ:
if Flag is 0, this e_Bmag2MPZ is the error of Bmag in the 2MPZ,
else e_Bmag2MPZ and e_Bmag2MPZ2 gives the predicted intervals in between
the real value falls with 95% probability
Note (3): For error on zph2MPZ:
if Flag is 0, this e_zph2MPZ is the error of zphot in the 2MPZ, else
e_zph2MPZ and e_zph2MPZ2 gives the predicted intervals in between the real
value falls with 95% probability
