Considering universality for all types of SAS, functionality of each stages and so on, I propose the naming on the digital system below. Type-A: F0 - F1 - F2 - F3 - BF - PF - MAR - IM - TM Type-B: F0 - F1 - BF - IM - TM Type-Bp: F1 - BF - IM - TM

(* Recoil-mass chain is omitted because this is a naming of the "stages") (* Sorry I'm not sure about the Type-C )
