Using a single AP for all sights is based on using Volume 1 of HO 249 and is chosen to be a whole number of degrees of LHA Aries at the chosen FIX time. If using volume 2 or 3 or other methods of computation then you need separate AP's for each body resulting whole number of degrees of LHA body at FIX time. Then you make the normal correstion for MOB and MOO.
