A dataset containing experimentally derived pathlengths for microplate wells
containing water at different volumes. Pathlengths were derived by using the
equation pathlength (cm) = kfactor_well / kfactor_1cm. Kfactor_well is
defined as A975-A900 value for each well (there were 4 replicates per volume
per experiment). Kfactor_1cm values were derived using the get_kfactor()
function for water at 26oC.
