VI photometry of Westerlund 1 and 2
Listed in IVOA Registry (Virtual Observatory)
We have carried out CCD observations of stars in the region of the open cluster Westerlund 1 through the V and I passbands.
Description
The direct images were obtained with the 24-inch telescope of the University of Toronto Southern Observatory situated at Las Campanas Observatory, Chile. After cross-correlating all independent V, (V-I) tables we have obtained a improved set of colour and magnitude values as compared to those based on a single measure.
