M4AST (Modeling for Asteroids) is a free on-line tool for modeling visible and near-ir spectra of atmosphereless bodies.

Detailed description and how to (.pdf file).

M4AST allows to model temporary (on-the-fly) anonymous file submission.

M4AST proposes several routines for spectral analysis:
- plotting the data;
- merging spectra;
- taxonomy comparison;
- comparison to laboratory measurements(RELAB database);
- de-reddening of spectra and comparison.

M4AST interface was tested under Google Chrome, Firefox 3.6, Internet Explorer 9, Konqueror, and Opera browsers.
