N₂H⁺ (3−2) integrated intensity (moment 0) map of the IRAS 16293−2422 environment computed in a velocity range between −1.3 and 7.9 km s⁻¹. The RMS of this map is σ = 0.23 K km s⁻¹. Contours are drawn at 3σ, in steps of 2σ between 4σ and 10σ and in steps of 10σ afterwards. The right sided color bar indicates the intensity of the emission in units of K km s⁻¹. The position of the protostellar system IRAS 16293−2422 A/B and the cold core 16293E are indicated. In addition, the positions of emission peaks previously identified by Walker et al. (1988) and renamed by Hirano et al. (2001) and Castets et al. (2001) called E1, E2, W1, W2, and HE2 are also included. The FWHM beam size is shown in the lower left corner.
