While not immediately obvious from the text, there's a lot of
#GaiaDR2 behind this impressive piece of work. Also, as pointed out by@spacetimekatie, 40 "dark" companions!#GoGettemGaia!https://twitter.com/adrianprw/status/1224714481240039424 …

Call me dull, but how did you get the H mag on the y-axis? The paper mentions cross-matching to
#GaiaDR2, but I don't find the word "parallax" anywhere in the paper. -
