    I ran a linear unmixing model that resulted in a mean RMS of 0.003365. The ENVI Help says that the units are meters. How do I interpret this number in the context of an unmixing model? Is this RMS reasonable? Thank you.

    RMS error images use the results of the abundance images to determine the overall error of all of the endmember abundance values for each pixel. RMS error images should appear as noise. If you see areas with distinct recognizable features in the RMS error image, that indicates that there are probably problems with the endmembers, or perhaps some are missing from your analysis. If you have more questions regarding this, you should contact ITT Technical Support directly.
