Dataset Galaxy catalogs Galaxies Radio Carbon monoxide Evolution Interactions ISM - radio lines Surveys File "table1.dat" contains the CIG number, and general data for the total CO sample. File "tale4.dat" contains the CIG number, and the velocity integrated 12CO(1-0) intensities, line width and central velocities for galaxies newly observed. File "tale5.dat" contains the CIG number and the molecular gas mass for the total CO sample. We characterize the molecular gas content (ISM cold phase) using CO emission of a redshift-limited subsample of isolated galaxies from the AMIGA (Analysis of the interstellar Medium of Isolated GAlaxies) project in order to provide a comparison sample for studies of galaxies in different environments. We present the ^12^CO(1-0) data for 273 AMIGA galaxies, most of them (n=186) from our own observations with the IRAM 30m and the FCRAO 14m telescopes and the rest from the literature. We constructed a redshift-limited sample containing galaxies with 1500km/s<v<5000km/s and excluded objects with morphological evidence of possible interaction. This sample (n=173) is the basis for our statistical analysis. It contains galaxies with molecular gas masses, MH2, in the range of ~10^8^-10^10^M_{sun}_. It is dominated, both in absolute number and in detection rate, by spiral galaxies of type T=3-5 (Sb-Sc). Most galaxies were observed with a single pointing towards their centers. Therefore, we performed an extrapolation to the total molecular gas mass expected in the entire disk based on the assumption of an exponential distribution. We then studied the relationships between MH2 and other galactic properties. 2014-05-13T10:22:56Z 2014-05-13T10:22:56Z 2011 dataset http://hdl.handle.net/10481/31659 10.30827/Digibug.31659 eng http://hdl.handle.net/10481/28373 http://creativecommons.org/licenses/by-nc-nd/3.0/ info:eu-repo/semantics/openAccess Creative Commons Attribution-NonCommercial-NoDerivs 3.0 License Universidad de Granada
