Spectral types fromuvbyβ photometry

Letter to the editor
  • Terry Moon


New diagrams are presented for the assimilation of MK spectral types withuvbyβ photometry, based upon reddening-free parameters calculated using revised reddening ratios and recently published values of meanuvby colours and β indices for a selection of MK spectral types.
