Notes. (a) Median value and 1σ equivalent dispersion (half difference between the 84th and 16th percentiles) for all the pixels with a fitted spectrum for each core or filament. (b) Obtained by integration of the NH3 column density maps after applying the primary beam correction, except for RNO 1 where the mass was taken as the product of the average column density and the areawith NH3 (1, 1) emission. The ammonia abundance assumed was X(NH3) = 1 × 10−8. (c) Kinetic temperature, obtained from Trot (Estalella 2017). (d)Sound speed and Mach number (see text).
