Results of the MC simulations for core #1. Frames (a), (b), and (c) show parameters obtained for the NH₃ (1,1) line, (c) and (d) for the (2,2) line. Frame (e) shows the distribution obtained for (1,1) temperature, (f) for (2,2), (g) for rotational temperature, and (h) for NH₃ column density. Black crosses show the values obtained from the CLASS fitting. The red dashed lines indicate the 16, 50, and 84 percentiles, the thin black dashed lines show the standard deviation, and the thick black dashed line shows the values obtained with the best-fit parameter.
