Notes. (†) The reference position corresponds to the carbon-chain peak from Hirota et al. (2004), but the dust peak is at RA, Dec = 04:24:34, 26:36:43 (J2000.0). Columns: (2) See Sect. 2.1. (3) Reference position (EQ J2000.0) in the maps of Fig. 2; (4) Systemic LSR velocity (in km s−1); (5) Central H2 densities in units of 105 cm−3.
