TA-DA: a Tool for Astrophysical Data Analysis

Abstract

We present TA-DA, a new software aimed at greatly simplify and improve the analysis of stellar photometric data in comparison with theoretical models, and allow the derivation of stellar parameters from multi-band photometry. Its flexibility allows one to address a number of such problems: from the interpolation of stellar models, or sets of stellar physical parameters in general, to the computation of synthetic photometry in arbitrary filters or units; from the analysis of observed color-magnitude diagrams, to a Bayesian derivation of stellar parameters (and extinction) based on multi-band data. TA-DA is available as a pre-compiled IDL widget-based application; its graphical user interface makes it considerably user-friendly. In this paper we describe the software and its functionalities.

AJ accepted. The software is available at http://www.rssd.esa.int/staff/ndario/TADA/ . Comments are welcome for future additions/updates to TA-DA
