Formulae for both the parallactic and the peculiar motions are derived for all the co-ordinate systems mentioned above. The general formulaeare given for the derivation of the mean errors in mean parallaxes. Formulae for computing the dispersion in parallax, distance, and absolute magnitude are also derived Publication: The Astrophysical Journal Pub Date: December 1936 DOI: 10.1086/143783 Bibcode: 1936ApJ....84..555S full text sources ADS | Related Materials (1) Reprint: 1936CMWCI.558....1S
