New keys added in v5.0.0 related to distance between crystals

[yere-qubio]

Hi, i was wondering if the distances specified in the following keys (introduced in v5.0.0):

Scanner parameters:=
normal parameters...
Scanner geometry (BlocksOnCylindrical/Cylindrical/Generic)  := BlocksOnCylindrical
Distance between crystals in axial direction (cm)           := 0.22
Distance between crystals in transaxial direction (cm)      := 0.22
end scanner parameters:=

refer to distance between crystal edges (that means, the gap between crystals) or to distance between the center of the crystals (that means gap + 2 * (axial crystal size / 2)).

Thanks in advance.

distance between the center of the crystals (that means gap + 2 * (axial crystal size / 2)).

This one. These variables refer to the pitch of the object. The same is used for the blocks.
