TA-DA is a user-friendly software tool that simplifies the analysis of stellar photometric data and enables the derivation of stellar parameters using theoretical models and multi-band observations.

Contribution

The paper introduces TA-DA, a flexible IDL-based software that streamlines stellar data analysis and parameter estimation from multi-band photometry.

Findings

TA-DA effectively interpolates stellar models and computes synthetic photometry.

It enables Bayesian derivation of stellar parameters and extinction.

The software is accessible via a graphical user interface.

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.
