TABLE 801. — Parallax and Mean Apparent Magnitude 



(Reprinted by permission from Russell, Dugan, and Stewart, Astronomy, Ginn & Co., 1927.) 



TABLE 802. — Spectrum Type and Mean Absolute Magnitude 



(Trumpler, Bull. Lick Obs., No. 420, 1930.) 



TABLE 803. — Reduction of Visual to Bolometric Magnitude 



Eddington (M. N. 177, 605) gives the corrections from visual to bolometric magnitudes 

 for the cooler stars. For the hotter stars the data are not so certain. The values are to be 

 added algebraically to the absolute visual magnitudes.
