VNIR chert reflectance data

Summary

The data consists of spreadsheets of VNIR reflectance data and sample provenience information. Each row is individual reflectance intensity values at specific wavelengths while columns represent the spectral signature for an individual chert sample. Also included are the Pearson's correlation coefficient tables. There are five text files in total each should be opened as an individual tab delimited spreadsheet. The first sheet is the uncorrected raw VNIR reflectance data for all of the samples, the second sheet is the data corrected for two vertical offsets which occur at the detector boundaries, the third is the derivative transformed spectra, the fourth is the entire Pearson's correlation coefficient matrix and the fifth illustrates the highlighted top two correlation scores per sample demonstrating the ability of the VNIR technique to differentiate chert types and potential to identify individual outcrops/deposits.
