A computational method for quantitative analysis by multiwavelength absorption spectroscopy, called the Tfit method, based on fitting a model of the instrumentally-broadened transmission spectrum to the observed transmission data. It has the advantages of wider dynamic range and greatly improved calibration linearity, compared to conventional methods. Run TFitDemo.m to see how it works. Version 2.1 Press K to display list of all keyboard commands. See http://www.wam.umd.edu/~toh/spectrum/TFit.html for more details.
