Abstract:
    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.

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.
