Real FEATHER_RANGE[2]
FEATHER_RANGE[2] defines a region of "overlapping" UV spacings over
which the ratio of LOWres and HIGHres visibilities can be checked. If
the flux scale is correct, this ratio should be 1. FEATHER_RANGE de-
faults to FEATHER_RADIUS/1.15 and FEATHER_RADIUS*1.15.
The computed ratio is only a guide, and not used in the algorithm. A
proper definition of FEATHER_RANGE requires knowledge of the initial UV
coverage of the HIGHres and LOWres data sets. If FEATHER_RANGE is too
large, the computed ratio has no real meaning.
