splice: Splice correction of a spectra collected using ASD hardware

Description Usage Arguments Details Value Author(s) Examples

Description

This is the correction method available in the ViewSpec Pro software from ASD, which aims at correcting steps in the data (see details).

Usage

1
2
## S4 method for signature 'Spectra'
splice(x, locations = list(c(750, 1000), c(1830, 1950)))

Arguments

x

a Spectra object

locations

the wavelengths to cut out and interpolate

Details

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.

Value

an object of same class as x
