Re: comparison of GSPC and USNO-based V mags

    I have prepared a similar comparison table on recently announced sequences
by Dr. Henden.  These sequence may be better than GSPC, esp. to the fainter
end.  The comtent of the table is like:

                        Henden's sequence                           USNO magnitudes
          R.A.     Decl      V      B-V    U-B    V-R    R-I   USNO A1.0 number   r    b  V_exp
