During the ASTRO-2 mission observations of
several clusters were scheduled by UIT to identify and categorize
hot stars in them. During these observations WUPPE (and HUT)
generally tried to point to a chosen star in the cluster
or near it in order
to obtain a observation (spectroscopy and polarimetry) of that
star alone. In a few globular clusters there were no suitable
stars available, and the pointing was made to the cluster center
to obtain an integrated cluster spectrum.
For several of the clusters WUPPE obtained polarimetry of individual stars which is being analyzed along with other stars in WUPPE ISM program.
For several others WUPPE obtained a spectrum.
