List of spectrophotometric standards from Jeremy Walsh.

  The HST spectrophotometric standards cover the approximate wavelength range  800 to 12,000 Angstrom.
The following table gives summary details for the standard stars.  It was assembled from SIMBAD (in July 2002) and
 consequently the data are somewhat heterogenous.  Similar data are available
 in Table 1 of Turnshek et al. (1990).  The Turnshek et al. and SIMBAD V
 magnitudes usually agree to within a few tenths of a magnitude, but there
 are some significant differences in the spectral types.  Turnshek et al.
give the following position for BPM 16274: 0 50 03.18, -52 08 17.4, which
 may be preferable to the unusually imprecise SIMBAD position.  An asterisk
(`*') in the final column of the table indicates that the star is also
 included in the companion set of Oke spectrophotometric standards.
