The files RoLeHe_* contain the ultraviolet spectra of hot stars used in
the evolutionary synthesis models of Robert et al. (1993; ApJ, 418, 749)
and Leitherer et al. (1995; ApJS, 99, 173). There are 51 files. Each file
contains a group of stellar spectra, averaged and rectified. The format
is ASCII. Column 1 is the wavelength in Angstroms, column 2 is the
normalized flux. The name of each file denotes the spectral type(s) of the 
stars in the particular group. For instance, o3-5i means there are stars of 
types O3I, O4I, and O5I. "p" stands for "." in intermediate spectral types, 
i.e. o6p5v means O6.5V.

31 stellar groups are based on IUE high-dispersion spectra of O stars and
4 groups are based on IUE high-dispersion spectra of Wolf-Rayet stars. All
35 groups are listed in Table 1 of Robert et al. (1993). This table also 
gives the identification of the stars used in the groups. The remaining 16
files contain B and early-A stars observed with IUE in its low-dispersion
mode. The original spectra (before rectifying them) were published by
Fanelli et al. (1992; ApJS, 82, 197).
