Fig. 8
Column densities for H2 along the TMC-1 filament. The dashed line represents molecular hydrogen column densities calculated with Eq. (3) while assuming a constant dust temperature of Td ≈ 11.0 K. The diamonds represent N(H2) values derived from a NICER extinction map as described in the beginning of Sect. 3.3. The triangles and the dotted line represent N(H2) values calculated by using variable dust temperatures obtained from Eq. (7).
