Notes. Listed in the first column are the ATOMIUM sources in which the velocity of all transitions of SiO is lower than that of CO v = 0 J = 2 − 1, v(SiO) < v(CO)). The second and third column list the ATOMIUM sources in which at least one SiO transition has a larger line width than the CO v = 0 J = 2 − 1 line, v(SiO) > v(CO). In the case where only SiO lines trace velocities larger than the CO v = 0 J = 2 − 1 line, the source is listed in the second column; if other molecules also trace a larger velocity, the source name is indicated in the last column. The largest radial extent probed by the high velocity lines of SiO in the 15 sources with v(SiO) > v(CO) is listed in Cols. (2) and (3). The maximum extent can be probed by SiO lines other than the one listed in Table 3.
