Notes. First values correspond to the compact and hot component (200 K, 0.35″), second values to the extended and cold one (60 K, 0.60″). For vibrationally excited transitions, HNCO and 13CH3OH, only the hot component was considered. (a)Using N(H2) = 1.4 × 1025 cm−2 at 0.35′′, and N(H2) = 1.1 × 1025 cm−2 at 0.60′′ (see text).
