Description:
We present observations of the 12CO(J=1-0) line at 2.6mm of 65
galaxies located in the Coma supercluster region: 33 actually belong
to the Coma supercluster while 32 are either foreground or background
objects. These data have been obtained using the NRAO 12m telescope at
Kitt Peak (United States), and for four galaxies, using the IRAM 30m
telescope at Pico Veleta (Spain). Out of these 65 galaxies, 54 had
never been observed in the CO(1-0) line; 49 have been detected by us,
of which 37 are new detections. We give molecular gas masses deduced
from the CO line integrated intensities, and upper limits for the 16
undetected objects, computed with a Galactic conversion factor
N(H2)=2.3x1020I(CO) and H0=75km/s/Mpc.
