BVI photometry in M55 (NGC 6809)
Listed in IVOA Registry (Virtual Observatory)
We have compiled the asymptotic giant, horizontal, and upper red giant branch (AGB, HB, and RGB) stars in the globular cluster M55 (NGC 6809).
Description
Using the star counts and the R-parameter we compute the initial helium abundance Y=0.274+/-0.016.
