The 2MZoA catalogue

We present a homogeneous 2MASX galaxy catalogue at low Galactic latitudes (|b|<=10.0deg, called Zone of Avoidance, ZoA) which is complete to a Galactic extinction-corrected magnitude of Ko0.95). This catalogue supersedes the previously presented bright 2MZoA catalogue which was only complete to Ko<11.25mag. It fully complements the 2MASS Redshift Survey (2MRS) galaxy catalogue, which has the same magnitude limit but excludes high extinction regions. The combination of the two catalogues, the extended 2MRS or e2MRS, is is a uniquely whole sky redshift survey and forms a sound basis for studies of large-scale structures, flow fields and extinction across the ZoA. The here presented catalogue comprises 6899 galaxies with 6757 galaxies at low latitudes and 142 galaxies in highly obscured high-latitude areas. The completion rate in redshifts is almost 75%. The catalogue is complete up to star density levels of at least logN*/deg^2^11.75mag and Ko,d<=11.75mag) to the sample. This extended sample shows good completion rates with extinction up to at least AK<1.3mag. Omission of such a diameter-dependent extinction correction may lead to a biased flow field even at intermediate extinction values as found in the 2MRS survey. As in our previous investigations, we do not find a dependence of the correction factor f=0.86 to the extinction maps on Galactic longitudes or latitudes, but note a possible influence by cosmic variance.
