    "The data for Venus has not been corrected for phase; under certain conditions this could displace the center of light up to 0.3 arcminutes."


    But the question is: why do you need to correct for phase when taking a sight with a marine sextant?
    And, what for the moon?

    If you eye is sharp enough and ones can see the spot of light, or the limb it is not necessary, isn't it?
