Correction of absolute magnitude

Almost all of the galaxies listed on this page have a minor error in the info template on the right in their article pages. The error is a false figure given for the absolute magnitude of the galaxy.

For example, for M51 the figure given for abs. mag. was 12.7 while the true abs. magn. is -21.5

However, 12.7 is roughly M51's surface brightness, so I assume the editor unwittingly picked the wrong value. Nevertheless, almost all of the galaxies listed here have to be updated. How to calculate the abs mag see the article. Albester 20:02, 14 May 2006 (UTC)[reply]
