We present the 12CO(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 ∼108-1010M. 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. Description: 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. File Summary:
