To solve this I again threw out the hyperclusters and went back to the raw imagery. A haze correction was performed following the procedures set forth by Lavreau (1991). In this technique a 4th tasseled cap transformation was created and used as a correction factor to create 6 corrected bands from the raw data. After this was complete supervised classification was performed on the corrected bands. For specific details on this technique see the referenced article (Lavreau 1991) in the figure.
