II/160 HST Colour System Isochrones (Edvardsson, Bell 1989)
================================================================================
Theoretical Colours and Isochrones for some Hubble Space Telescope Colour

Description:
This dataset contains two related data types.
The first (1 file) is a grid of synthetic surface brightness magnitudes
for 21 of the Hubble Space Telescope Wide Field Camera (WFC) pass bands.
The magnitudes are calculated from a new set of synthetic spectra for
effective temperatures in the range 4000 to 7250 K, surface gravities
typical of dwarfs and sub-giants, and for metallicities in the range solar
to one-thousandth solar (280 synthetic spectra).
The second is the absolute magnitudes for each of the 21 pass bands for a
set of globular cluster isochrones with different helium abundances,
metallicities, oxygen abundances and ages. The isochrones were taken from
VandenBerg and Bell (1985), Bell and VandenBerg (1987), Hesser et al.
(1987) and McClure et al. (1987) all of whom originally published them for
the Cousins VRI, Johnson UBV, Stromgren and Thuan-Gunn photometric
systems.
