The positions as used were taken from pp. 30-108, where they are 

 given uncorrected for proper motion, and, in the case of ephemeris 

 stars, with certain periodic terms neglected (cf. Introd., p. ix). They 

 are repeated, with these corrections applied, in the General Catalogue 

 on pp. 109-120. In each case, however, the amount of the correc- 

 tion, with its proper sign, is set down in column 9, under the head 

 Aa (Introd. p. xv).
