Corwin's Notes
=====
NGC 5390 is probably a reobservation of NGC 5371. JH saw the objects in
different sweeps, and marked both the RA and Dec of N5390 uncertain (single
colons published in the 1833 list, double colons in the sweep itself). His
north polar distances are the same, but the RA is two minutes too large for
N5390, probably the result of a differential clock reading for the object as
it was leaving the field.
His description for N5390, "F, L, vgbM; has a * 9m, nf, 4 arcmin dist," would
match N5371 but for one detail: the star is only 2 arcmin distant, and there
is another star, nearly as bright, 5 arcmin north-northeast. Unfortunately,
he did not attach a description to his correct position for N5371, so the
identity is not absolutely sure. But it is a suggestion from Reinmuth,
carried over by Carlson, so has been in the literature for some time.
I suspect that the two minute error is the result of a hurried observation,
and that the two entries actually do refer to just the one galaxy.
