Description Nicola Baldo 2011-05-03 05:56:56 UTC

The spectrum-value test checks if two SpectrumValue instances match by testing the norm of the difference between the two spectrum values against a tolerance. This is not appropriate because the effect of the tolerance is proportional to the norm, which gets larger as the number of elements in the SpectrumValue (i.e., the number of bands in the SpectrumModel being used) get larger.

The correct behavior is to test equality within tolerance on a per-element basis.
