Summary: | We present a coarsely sampled map of the region o l o 2¡, o b o 0¡.1 in the 492 GHz (3P] 3P) Ðne-structure transition of neutral carbon, observed with the Antarctic Submillimeter Telescope 1 and 0 Remote Observatory (AST/RO). The distribution of [C I] emission is similar on the large scale to that of CO J \ 1] 0. On average, the ratio of the integrated intensities, I /I is higher in the Galactic *C I+ 12CO, disk than in the Galactic center region. This result is accounted for by the absorption of 12CO within the clouds located in the outer Galactic disk. The ratio I /I is surprisingly uniform over the variety *C I+ 12CO of environments near the Galactic center. On average, [C I] is optically thin [or as optically thin as 13CO (J \ 1] 0)], even in the dense molecular clouds of the Galactic center region. |
