Filter out the high wavelength values

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

remove_head(signatures, head)

Arguments

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

Value

The processed (low wavelength filtered) signatures.
