Investigate/comment on differences between various OS's

It has been observed that the coverage plots can be dramatically different between OS's. In an effort to try and locate what causes the difference a simple comparison was performed, all data files were shared over the same NFS structure to remove any variation. the outputs listed here are the first 15 lines of the Numeric output file to remove any differences in TIF PNG JPEG GDAL libraries.
