Hello,

When I tried to visualize the signature file created with i.class what I got was:

I Know that the number in the first row is the number of pixels within that region.
The numbers in the second row are the mean for each spectral band.
And the other numbers I don't understand what they mean!!

Can someone give me some hints about the meaning of this?

Thanks
