[vsnet 605] Markarian 421 comparison sequence typo

Bob Modic has pointed out that in the combined comparison sequence for
Markarian 421 I sent out about ten days ago [vsnet 595], the magnitude for the
star GSC 3010-0733 is listed incorrectly due to a typographical error on my
part. It was given as V=11.39, but should be V=10.39, in accordance with the
AAVSO chart. The complete table is given again below with the typo fixed.
My thanks to Mr. Modic for pointing out this correction.
