Catalogue of stellar spectra classified in the Morgan-Keenan System : Serie Astronómica - Tomo XXVIII, no. 2

The purpose of this catalogue is to provide bibliographic references to spectral classifications of stars in the Morgan-Keenan system published in the literature prior to January 1963. The catalogues include with fey exceptions only objects contained in the Durohmusterungen: HD, SBD, CD and CPD. Obj...
