Radiometric anomalies were quantified by using the ratio of ek:eTh.
A ternary image of the KUT data field was produce after gridding the data with 200m cells.
To smooth the data, but retain the statistical advantage of the large 200m cells, the data
was interpolated to 50m cells after the nearest neighbour (NN) gridding done at 200m.
Note this is not the equivalent of gridding using 50m cells - the grid is controlled by the 200m grid nodes of the parent 200m NN grid.
This was compared with the K:Th ratio - highs in the K:Th ratio corresponded with areas of
interest seen in the KUT RGB ternary image.
Anomalies were identified as 1 standard deviation and 2 standard deviations from the average of the K:Th image grid.
The K:Th ratio data set has a near normal histogram.
1 standard deviation is 0.15, with an image average of 0.31
The evidence space is built with the following values:
using 1 and 2 sigma anomaly levels produces a very spotty map, so these were relaxed to 0.66 and 1.3 sigma anomaly levels for Oprah
	0 when K:Th <0.40
	1 when 0.40 <= K:Th < 0.50
	2 when K:Th >= 0.50
