Notes. 

(a)

Segment in the proper motion diagram (Fig. 6).

(b)

Number of stars per bin.

(c)

Average of the slopes derived for 1000 realizations of randomly distributing the remainder of the division of the number of stars by the number of bins into the bins by increasing the number of stars in the selected bin by one.

(d)

Formal uncertainty of the linear fit.

(e)

Maximum difference between the slopes due to the random distribution of the surplus stars.
