Comparison of the gas mass-loss rate values for the common sources between our work and those by Groenewegen et al. (2009) and Groenewegen & Sloan (2018) (left diagram) and Riebel et al. (2012) (right diagram). The uncertainties plotted are only the ones derived in this study. The cross in the bottom right corner of the right panel represents the average uncertainty. We note that the average uncertainty depends on the mass-loss regime, as is clear in the left panel.
