Results of the MC simulations for 1446. Frames a, b and c show parameters obtained for the NH₃ (1,1) line, c and d for the (2,2) line. Frames e and f show the distribution obtained for main beam brightness temperature, T_MB(1, 1) and T_MB(2, 2), g for rotational temperature and h for the NH₃ column density. Black crosses mark the values obtained from the CLASS fitting. The black thick dashed lines show the values obtained with the best fit parameter, the black thin dashed lines show the standard deviation, and the red dashed lines indicate the 16th, 50th, and 84th percentiles.
