
After the measurements the data are downloaded and the calibrated waterbase and
Nigrosin spectra are imported into the database of msda_xe .

The calculation of the reflectivity is performed with the averaged spectrum of pure
water measured before the Nigrosin measurement.

The reference Nigrosin measurement is imported from clipboard as described in
chapter 4.2.1.

The reflectivity is calculated.
6.3 Reference spectrum of Nigrosin
The following figure shows an example of the nigrosin reference measurement with an
absorption spectrometer Perkin Elmer Lambda 850.
