Interactive 3D and 2D plotters for the combined ALFALFA + HIPASS HI source catalogue (~35,000 galaxies).
index.html— 3D Cartesian view (x, y, zfrom RA, Dec, distance), with drag-to-rotate, auto-spin, distance clipping and survey filter.2d.html— Generic X–Y scatter plotter for any pair of catalogue columns (RA, Dec, V_hel, W50, HI flux, distance, log M_HI).combined_HI.csv— Merged catalogue. Source: ALFALFA α.100 (Haynes et al. 2018, ApJ 861, 49) and HIPASS HICAT (Meyer et al. 2004, MNRAS 350, 1195), via VizieR. HIPASS distances are naïve cz/H₀ at H₀ = 70.
