Ends of Dataset
To ensure that the smoothing function is applied uniformly over
the whole data array, it is treated differently at the edges.
For instance, at pixel one, half of the smoothing function will
lie outside the array. The ends of the dataset are temporarily
extended by half of the width of the smoothing window while
being smoothed using one of the following user selectable
techniques (controlled by the value of the ENDS parameter),
- ENDAVERAGE
- Extend each end with a local average over n pixels at
the end of each strip.
- REGIONAVERAGE
- Extend each end with an average over two user specified
pixel ranges.
- ONESPECIFY
- Extend each end with one value
- TWOSPECIFY
- Extend each end with a separate value
- ENDVALUE
- Extend each end with the first and last values in the
strip.
