Type: Adverb (String*2)
Use: Specify weighting function used to equalize coverage of measured
points in UV plane and otherwise adjust the weights. It is a two
character code. If the first is 'N' then there is no correction
to the data weights for the local density of samples or weights.
If it is 'C', then the weights are corrected for the local
density of samples (simple counts). Otherwise, the weights are
corrected for the local density of data weights (so-called
uniform weighting). The second character causes the weights to
be modified before the local density of weights is measured and
again before they are used. If the second character is the
letter 'V', the fourth root of the weights is taken; if it is 'S'
the square root of the weights is taken; and if it is the
letter 'O' all weights are taken as 1.0.
Null Value: ' '
Null value means Uniform weighting with no conversion of
