Solving these equations we obtain

W" = — 06750 R 
and 
2 = 1.3079 R 
which value combined with the value of 2 in (11) gives 
(16) R = 345 
corresponding to an absolute magnitude 
(16*) M = — 2" . 
The value of R comes out more than one Siriometer smaller 
than from the brighter stars. The explanation of this anomaly will 
be discussed below. 
Even the normal equations from the right ascensions or the 
declinations alone lead to similar values of R.
