The Main Sequence of NGC 6231 and the Calibration of Absolute Magnitudes
Published online by Cambridge University Press: 14 August 2015
Extract
It is fitting to mark the Centennial of Henry Norris Russell's birth with a discussion of a new approach to the calibration of absolute magnitudes for MK spectral types. With the addition of the NGC 6231 main sequence down to A0, the material for the cluster fitting method using very carefully determined MK types is complete. The data will be published elsewhere (Garrison and Schild 1978).
