All Tables

Table 1: Observed sources. Columns 2 and 3 give the equatorial coordinates. Columns 4-5 present the galactic coordinates. The $V_{\rm LSR}$ of the water maser peak velocity is listed in Col. 6. NH₃ detection is shown in Col. 7. The last column gives the distance.
Table 2: Observed parameters. Column 2 lists the reference position (see Table 1) and peak position of the NH₃ core. The main beam temperature, the LSR velocity, the line width, the optical depth of the main hyperfine component and the peak value of the integrated intensity of the (1, 1) line are given in Cols. 3-7. Columns 8-12 and 13-17 are the same items as Cols. 3-7 but for the (2, 2) and (3, 3) lines.
Table 5: Average properties of NH₃ cores.
Table 3: Derived parameters. Column 1 is the source name, Col. 2 is the angular size of the source, Col. 3 is the linear size of the source assuming a spherical geometry. Rotation temperature of the (2, 2) and (1, 1) transition, rotation temperature of the (3, 3) and (2, 2) transition, kinematic temperature and excitation temperature of the (1, 1) line are listed in Cols. 4-7, respectively. Volume density of H₂ is listed in Col. 8. Column density of NH₃ and the corresponding H₂ volume density ${n_{\rm H_2}\rm (NH_3)}$ are listed in Cols. 9 and 10, respectively. Its mass, virial mass, and the density derived from the virial mass, ${n_{\rm vir}}$ are listed in Cols. 11-13, respectively.
Table 4: IRAS and 2MASS parameters. The two parts of the table give out the detected and un-detected sources respectively.
