RM = — (9,522 + 0.053 , 
where the results are expressed in radians (9) per stellar year. 
Through a comparison with the values of U,", V,", W," in (10), 
the value of 1/E, is obtained. This determination is best performed 
through a comparison between 
yU,'? + UE JE Ww," = (oy 
and 
From (10) we get

Comparing the values we get

This equation gives, more strictly expressed, the mean value of 
1/R and ought to be denoted by
