Filter out the low wavelength values

Data preprocessing to remove the lowest wavelengths for each signature, possibly because of noise.

remove_tail(signatures, tail)

Arguments

signatures	A spectral object built using the load_signature_files function.
tail	The wavelengths from tail to the maximum will be removed.

Value

The processed (high wavelength filtered) signatures.
