These data are from soluble absorption coefficients measured every 2 nm from 300 nm to 750 nm.

These data were originally processed by Greg Mitchell's Lab at SIO.
See Greg Mitchell for questions (gmitchell@ucsd.edu).
References to processing procedures are below.

The raw data was fit to an exponential and then that fit was used to calculate the fit dat presented here: as_fit(lambda) = a0_300*exp(-slope)

The units for the soluble absorption coefficient as are (1/m).
