Afaik dark matter content is calculated by the rotation speed of the galaxy. I'm not clear why the distance errors wouldn't average themselves out over the rot

- The_rationalist 5y agoOnly considering rotation speed for MOND seems like a simplist, poor approximation. One needs to take into account how wide/large is the galaxy. Its 3D shape. And a map of its local main density/sparsity points with estimated masses. A failure to estimate accurately any of those metrics seems like the issue with this galaxy, not MOND itself.
