We present a coarsely-sampled map of the region |l | ≤ 2 ◦ , |b | ≤ 0.1 ◦ in the 492 GHz ( 3P1 →3 P0) fine structure transition of neutral carbon, observed with the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO). The distribution of [C I] emission is similar on the large scale to...
