No other measures since 1867. The principal star is given a 
small proper motion:

The measures of the two more distant companions are now 
sufficient for a very accurate determination of the proper 
motion of the two principal components. From the measures 
of AC (1879-1912) and of AD (1829-1912) we have for the 
motion of A:

in the former measures appears to be too small.
