Hello Geoff--The 360 Degree technique sounds good here.  A 10:1 ratio no
doubt is an ideal.  I guess when you get "tighter" than that, an event
readout is compressed in size.  It would be neat (for comparison purposes)
to be able to have different ratios exhibited by the same sensor on the same
event!!  Thanks--Jim
