Thank you for the criticism! My input data only contains celestial coordinates: - Right ascension in arcminutes - Declination in arcminutes
I can perhaps try to get some redshift data and implement the 3D position for each galaxy. Great idea! Thank you!
Andromeda we have pretty-well established at 0.78 MPc, and M32 at 0.77 MPc.
NGC 7768 at 120 MPc.
Whereas the largest galaxy we currently know of, ESO 383-G 076, is at 200.59 ± 14.12 MPc. That gives a variability in distance far larger than the distance to most of our nearby closest galaxies!
