Splice correction of a spectra collected using ASD hardware
This is the correction method available in the ViewSpec Pro software from ASD, which aims at correcting steps in the data (see details).
## S4 method for signature 'Spectra' splice(x, locations = list(c(750, 1000), c(1830, 1950)))

The SWIR1 part of the spectrum (1000-1800 nm) is taken as a reference for corrections as it is stable to the instrument sensitivity drift (Beal and Eamon, 2010)
This is based on a description of the splice correction algorithm described in:
Beal, D. and Eamon, M., 1996. Dynamic, Parabolic Linear Transformations of 'Stepped' Radiometric Data. Analytical Spectral Devices Inc., Boulder, CO.
