Statistical analysis of the errors in visual double star observations. II - 'New-generation' observers
Data from micrometric observations of visual double stars are compiledin extensive tables and graphs and analyzed statistically, extending thestudy of Pannunzio et al. (1986) to include observations obtained after1930. Residuals are computed for the entire sample, for instrument sizeclasses, and for single observers. The effect of resolving power seen inthe old-generation observations is confirmed, and the applicability ofthe complete data set to derivation of corrective weighting coefficientsis indicated.
