from carbspec import spectro # for doing the work
spec = load_spectrum('./SI/data/pH/CRM1_DICKSON_D10_CRM_100211_03_12_2019.dat') # this data file is in the 'SI' folder of the reposiitory.
# NB Yo don't have to use 'load_spectrum' - the following function just requires two arrays containing wavelength and absorption.
