Prochloro_Normalise_F

Normalizes pigment ratios differently for Prochlorococcus vs other groups,
using divinyl chlorophyll a for Prochlorococcus and chlorophyll a for others.

internal

Determine the chlorophyll a (Chl a) concentrations of different
phytoplankton groups based on their pigment biomarkers. The method uses
non-negative matrix factorisation and simulated annealing to minimise error
between the observed and estimated values of pigment concentrations
(Hayward et al. (2023) <doi:10.1002/lom3.10541>).
The approach is similar to the widely used 'CHEMTAX' program
(Mackey et al. 1996) <doi:10.3354/meps144265>, but is more straightforward,
accurate, and not reliant on initial guesses for the pigment to Chl a
ratios for phytoplankton groups.
