The construction of a track model at variable azimuthal resolution, with higher
resolution around the track joints, might allow more rapid data acquisition in
the Point-Wise mode. Some data was taken with normal resolution of 1degree and
a higher resolution of 0.1degree around the track joints, but it proved
problematic to reduce. At the change in resolution we see apparent
zero-point shifts, amounting to +3" in Ch 5 and -3" in Ch 8,
with a reversal of shift when the resolution changes back.
No explanation is offered at this time. The use of mixed resolution data is
considered improbable in the light of the much better performance achieved with
other modes of operation.
