Results of the ESO-SEST Key Programme: CO in the Magellanic Clouds. V. Further CO observations of the Small Magellanic Cloud

We present further results of fully-sampled observations in the J =1 ! 0a nd J =2 !1 rotational transitions of 12 CO and 13 CO, obtained with the SEST telescope at 43 00 or 22 00 resolution, toward the Small Magellanic Cloud. These observations concern six molecular clouds with a variety of physical conditions. Maps in the 12 CO(1!0), 12 CO(2!1), and in some cases of 13 CO(1!0) lines are presented, as well as proles of the four lines at the peak positions convolved to the same angular resolution of 43 00 . The line ratio results are interpreted in Paper IV of this
