Re,


>It IS NOT NECESSARY  to use a full aperture flat to test a primary mirror.


One could put the subaperture flat on a sliding kinematic
carriage, with the usual tilt adjustments on the flat.
The flat is aligned to the primary positioned to be concentric
with the primary, then slid laterally to view the surface
between the edge and center of the primary. Note that the slide
does not neer to be aligned to the optical axis, just that it
traverses without changing the normal to flat.
