    Re: NA "v" correction & mercury observations
    From: Gary LaPook

    But it's easy enough to compare the consecutive GHA tabulations and determine the "v" correction factor which is just the difference between the two tabulations and then use the "corrections" table in the N.A. to improve the GHA. I find it surprising that the N.A. doesn't just list a "v" correction for the sun.
