Table 1: The permanent dipole moments of the molecules and the rest frequencies of the observed transitions.
Table 2: Estimates of the $\ensuremath {{\rm HCN}}$ (J=1-0) excitation temperatures and the $\ensuremath {{\rm HCN}}$ column densities towards selected positions using hyperfine structure fits. The coordinates are offsets from the position of Cha-MMS1a.
Table 3: Column densities towards the $\ensuremath {{\rm HN^{13}C}}$ maximum derived using the LTE method. The assumed value for $T_{\rm ex}$ is 5.2^+1.0_-0.6 K. ^a The intensity value is for the weakest hyperfine component F=0-1 which comprises one ninth of the total intensity of the J=1-0 line.
