Distance

edit

I think the distance cited in the article is incorrect. NED gives a luminosity distance of 11.1 Mpc, or 36 Mly, not 19 Mpc as given in the wiki article. The citation for the distance given is more recent than the NED distance, but I was unable to find the distance listed in the paper. Could someone clear this up for me, i.e. help me find the distance listed in the paper if it was there? Thanks, --Keflavich 22:44, 15 January 2007 (UTC)Reply

On page 685 of the article it has in the table that NGC 4548 has a distance modulus of 31.42 ± 0.54 which should convert to the value in the article if you do the computation. Per Dr. <mm do not put much faith in the NED distances for galaxies. WilliamKF 22:57, 15 January 2007 (UTC)Reply
NED uses a flow-corrected distance model that is not going to work for galaxies in the Virgo Cluster. The peculiar velocity of the galaxies is too high. M91 (NGC 4548) lies right inside the Virgo Cluster. The SBF estimate is going to be much more reliable anyway. Dr. Submillimeter 23:01, 15 January 2007 (UTC)Reply
