[edit] Distance

NED gives a drastically different distance than is cited in the article: http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=m+90&extend=no&out_csys=Equatorial&out_equinox=J2000.0&obj_sort=RA+or+Longitude&of=pre_text&zv_breaker=30000.0&list_limit=5&img_stamp=YES gives Luminosity Distance  : 1.22 Mpc (m-M) = 25.43 mag and D (Local Infall)  : 1.84 +/- 0.15 Mpc (m-M) = 26.32 +/- 0.17 mag 1.22 Mpc = ~4Mly, not 60. I'll correct it in the article, but could someone let me know how it got to be 60 Mly? --Keflavich 22:33, 15 January 2007 (UTC)

DO not trust NED's distance estimates, especially for galaxies in the Virgo Cluster such as NGC 4569. NED's calculation are based on flow-corrected distances which are going to be inaccurate for the environment around the Virgo Cluster. This galaxy should be listed as much further away. I am reverting the article. Dr. Submillimeter 22:53, 15 January 2007 (UTC)
