finding binding
boundThe luminosity of the Horizontal Branch (HB) is measurably correlated with metallicity and age, making unambiguous HB distance determinations difficult; when calibrated against globular cluster parallaxes, HB distances show ~0.2 mag scatter relative to TRGB, limiting standalone utility.
