Abstract
In order to study the excitation conditions in the Orion-A region, we applied an LVG code to 12CO, 13CO and C18O data obtained with the AT&T Bell Laboratories 7-meter telescope in USA (CO isotopes: J = 1−0, CS: J = 2−1) and the radiotelescope of the ”Groupe d’Astrophysique de Grenoble“ in France (CO isotopes: J = 2−1).
