THE ROSETTE MOLECULAR-COMPLEX - I - CO OBSERVATIONS

We present (CO)-C-12,(CO)-C-13 and C-18 O J = 1 --> 0, and (CO)-C-12 a nd (CO)-C-13 2 --> 1 and 3 --> 2 observations of the Rosette Molecular Complex (RMC), obtained with the KOSMA 3m and IRAM 30m telescopes. We introduce a method for correcting error beam pick-up of single-dish t elescopes in spectral line radio maps by using observations of a small er telescope and apply it to correct the IRAM 30m data presented in th is paper by the large scale KOSMA 3m data.
