<SUP>12</SUP>CO(1-0) and <SUP>12</SUP>CO(2-1) line intensity maps are p survey. NUGA observations have been carried out with 6 antennas of the PdBI in the ABCD configuration of the array and with the IRAM 30m single dish telescope. <P />For NGC 4569 and NGC 4826, we have also <SUP>12</SUP>CO(3-2) line intensity maps obtained with the Submillimeter Array (SMA) in its compact configuration with seven working antennas. <P />We retrieved Hα emission-line images from the Hubble Legacy Archive (HLA) that makes available HST WFPC2 observations of our galaxy sample.
