A (CO)-C-12(1-0) survey of spiral galaxies in the region of the Coma supercluster

We present observations of the (CO)-C-12(J=1-0) Line at 2.6 mm 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 12 m telescope at Kitt Peak (United States), and for four galaxies, using the IRAM 30 m 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(H-2)=2.3 10(20) I(CO) and H-0=75 km/s/Mpc.**
