The distant star is measured for determining hereafter how 
much, if any, of the proper motion is in the small star B. 
The measures give for the proper motion of A:

Very little relative motion. Appears to be a pair of the 61 
Cygni class. The proper motion of the larger star is given: 
Porter o"466 in 301 °6 
Kustner 0.442 in 302.1 
A third star should be connected.
