Thanks! The motions detected are pretty subsonic, so probably aren't expected to affect the hydrostatic equilibrium assumption significantly. We're measuring bulk flows, however, and not the turbulent width. There are some other recent observational results suggesting that the hydrostatic assumption isn't too bad: https://arxiv.org/abs/1805.00034 https://arxiv.org/abs/1805.00034 Yes - there was a lot of work behind this paper, and most of it was on trying to get the calibration procedures we developed to work. It was a long process of trying things and seeing what worked and testing the results for consistency. Initially I thought it would be a lot simpler, but real detectors in space are complex things.
