Notes. Columns are (from left to right) the object, J2000 right ascension and declination of observed position, distance, mass-loss rate from the literature, terminal expansion velocity (from CO data), FWZP LSR velocity range with observed emission, integrated main-beam brightness temperature, as well as mass-loss, outer radius of the NH₃ distribution (in cm and in arcsec), and [NH₃/H₂] abundance ratio derived from our modeling. For the range and for each source, the first and second rows give the values for the NH₃ and the H₂O lines, respectively. Numbers in braces relate to the following references for distances and mass loss rates: {1} Hale et al. (1997); {2} Decin et al. (2010); {3} Choi et al. (2008); {4} Decin et al.
