[vsnet-id 676] SMC deep sequence and new variables

The lists below show accurate coordinates for a UBVI sequence in the
Small Magellanic Cloud, and a list of new variables in the same region
recently published by Sharpee et al. (2002AJ....123.3216S).
For the photometric sequence, I have taken averages of the multiple
entries in the paper and rounded things to 0.01-mag. precision (errors are
typically ~0.02 mag.). Star A in the list was published with a typo in the
RA minutes (should be 04m, not 05m). The coordinates come from either UCAC1
or 2MASS. The list is sorted in order of decreasing brightness.
For the mostly fainter variables the positions come from GSC-2.2 or 2MASS
with a few exceptions. In addition, I show mean V magnitudes from Table 6
of the paper rounded to 0.1 mag. I matched the list against GCVS v4.1 and
found that several of the stars are already known variables with designations
as shown in the last column. Most of the brighter stars (V ~16) are cepheids
while the fainter stars (V ~19) are RR Lyraes.

51 no astrometric catalogue position available, but source position
is okay.
