II/63A              Balmer Lines Photometric Data     (Mermilliod+ 1980)

A Compilation of Balmer lines photometric data Mermilliod J.C., Mermilliod M. <Bull. Inform. CDS 19, 65 (1980)> =1980BICDS..19...65M
ADC_Keywords: Balmer lines ; Photometry, hydrogen-line Description: The purpose of the catalogue is to collect the photometric determination of the Balmer line-strength. Eleven different systems, including the measurements of one or more lines, from Hα to Hδ, have been found when surveying the literature. These include alpha, beta, gamma, alpha,beta, beta,gamma, and alpha,beta,gamma from various authors. The Stroemgren Hβ photometry is not not included in this version. File Summary:
