Table B.1

Ammonia column densities in the Chamaeleon cores.

Transition	N_l(MMS1) (cm⁻²)	N_l(C2) (cm⁻²)
NH₃ (1,1)	1.41 × 10¹⁴	5.43 × 10¹³
NH₃ (2,2)	5.39 × 10¹²	2.08 × 10¹²
NH₃ (3,3)	7.41 × 10¹⁰	–

Note: Calculations assume T_ex =7.6 K and 5.5 K for Cha-MMS1 and Cha-C2, respectively, as derived from the HFS fit to the NH₃ (1,1) lines.
