file will automatically be appended to

if acquisition is stopped and started

again later.

field spectra.txt Auxiliary sensor data and field data in

absorbance extracted and transformed.

Figure 2

The first 17 columns of the field spectra file represent the auxiliary sensor data (see

glossary for definition), each is labeled by a header, following the header is the

wavelength values. The next 384 columns are the absorbance data at each wavelength.

A value of –1 represents no data was present at that time.

Probe field spectra.txt This is output after the extraction

is ran and has all the hole

data interpolated to the same

depth increments.

cleaned field spectra.txt Filtered field spectra can be used

for applying calibration.

loadings.txt Principal components loadings.

PC_scores.txt Principal component scores.

interp_PC scores.txt Interpolated PC scores.

proposed_locations.txt Proposed sample locations

based on clustering.

actual_locations.txt Actual locations stored during

sampling program.
