Notes. Number of YSOs with detections of the two lines in the ratio (N), minimum (Min) and maximum (Max) value of the ratio, mean ratio value (Mean) and standard deviation (Std) is given for the observed line ratios. Model line ratios are calculated for three values of pre-shock densities, nH = 104, 105, and 106 cm-3, and three values of shock velocities, v = 20, 30, and 40 km s-1. See Table A.1 for the full identifiers of the lines.
