Description


This catalogue contains 4095 published observations of the quantitative observations of H{alpha} for 2700 stars. These observations were collected from values published between 1949 and 1980. The H{alpha} index was reduced to a common system described by Strauss & Ducati (1981A&AS...44..337S); the values of the original index can be retrieved with a linear transformation (cc = correlation coefficient): ----------------------------------------------------------------- References a b cc lower upper Spectral range ----------------------------------------------------------------- 2 1.401 -1.604 0.972 1.050 1.170 10 1.33 -2.4 0.000 13 1.526 0.130 0.992 2.910 3.300 14,36 0.343 0.814 0.949 1.400 O B A0 14,36 0.269 0.969 0.972 1.470 A1 F G K M 20,21,22,23,37 0.39 -0.55 1.200 24,25 1.35 -1.48 0.922 1.020 1.170 -----------------------------------------------------------------
