Doug's Excellent Absorption Law Calculator

This calculator determines the total absorption at wavelengths between 0.10 and 3.33 um using the algorithm determined by Cardelli, Clayton, and Mathis (1989) [ApJ 345 245] .

Required input parameters are:

Commonly accepted values of R_V are 3.1 for the Milky Way and 3.3 for the LMC. No sanity check of input parameters is currently done.

To obtain the total absorption in mags at the target wavelength, enter the appropriate values and then press the Compute button.
