Type: Adverb (Real)
Use: The radius in cells of the smoothing box used for uniform
weighting. All visibilities within a box of this radius of a given
visibility will be used to compute the weight if uniform weighting
For example, UVBOX=0 means that a visibility weight is determined
from the number of visibilities occuring in the same cell. UVBOX=1
uses the number of visibilities occuring in the 9 cells centered on
the cell in which the visibility in question occurs; UVBOX=2 uses
25 cells etc. The actual weight counted depends on the UVBXFN -
the weight can be counted fully or reduced by some function as it
gets farther from the cell on which it is centered. The size of
the cells in the UV plane is set by
1 / (CELLSIZE(i) * UVSIZE(i))
with some correction for units.
Null value: 0 => just use the cell in which the data sample
occurs for weighting
