Corwin's Notes
=====
NGC 4624 = NGC 4665 = NGC 4664 (which also see). JH notes that the "RA [is]
ill-observed," but did not mark it uncertain. During the same sweep, he made
a one-degree error in the polar distance for NGC 4636, an error that he
himself suggested, and that Dreyer finally rectified for the NGC. Thus, NGC
4624 cannot be NGC 4636 as suggested by Reinmuth and adopted by RNGC.
Instead, it is most likely NGC 4665 which JH described as "B, pL" in two
other sweeps. This, and the appearance of the bright bar of the galaxy,
matches his terse description for N4624, "B, E." In addition, his
declination is correct for all three observations.
There is a faint possibility that N4624 is N4600, but JH's two observations of
that make it "F, S" in contrast to his note on N4624. In addition, the
declination of N4600 is off JH's measured dec for N4624.
