Stray Light in Absorption Spectrophotometry. III. A Survey of Methods for Evaluating Stray Light Levels and Stray Light Corrections

An experimental survey of the estimation of stray light levels and corrections has been carried out. The performance of methods requiring no special instrumentation has been evaluated and compared. A new method, as convenient as the currently used filters method and capable of yielding better results especially when large stray light corrections are required, has been established and tested.
