We present an improved version of FIT3D, a fitting tool for the analysis of the spectroscopic properties of the stellar populations and the ionized gas derived from moderate resolution spectra of galaxies. This tool was developed to analyze integral field spectroscopy data and it is the basis of PIPE3D, a pipeline used in the analysis of CALIFA, MaNGA, and SAMI data. We describe the philosophy and each step of the fitting procedure. We present an extensive set of simulations in order to estimate the precision and accuracy of the derived parameters for the stellar populations and the ionized gas. We report on the results of those simulations. Finally, we compare the results of the analysis using FIT3D with those provided by other widely used packages, and we find that the parameters derived by FIT3D are fully compatible with those derived using these other tools.

Resumen (otros idiomas)

Presentamos una versión mejorada de FIT3D, una herramienta de ajuste para el análisis de las poblaciones estelares y el gas ionizado en espectros de galaxias de resolución intermedia. La misma se desarrolló para el análisis de datos de espectroscopía de campo integral y es la base de Pipe3D, un dataducto usado en el análisis de datos de los muestreos CALIFA, MaNGA y SAMI. Describimos la filosofía y los pasos seguidos en el ajuste, presentando un conjunto amplio de simulaciones con el fin de estimar la precisión de los parámetros derivados, mostrando el resultado de dichas simulaciones. Finalmente, comparamos el resultado del análisis con FIT3D y el obtenido mediante otros paquetes de uso frecuente, encontrando que los parámetros derivados son totalmente compatibles.

This study used data provided by the Calar Alto Legacy Integral Field Area (CALIFA) survey (http://califa.caha.es/). CALIFA is the first legacy survey performed at Calar Alto. The CALIFA collaboration would like to thank the IAA-CSIC and MPIA-MPG as major partners of the observatory, and CAHA itself, for the unique access to telescope time and support in manpower and infrastructure. The CALIFA collaboration also thanks the CAHA staff for the dedication to this project. This research is based on observations collected at the Centro Astronómico Hispano Alemán (CAHA) at Calar Alto, operated jointly by the Max-Planck-Institut fur Astronomie and the Instituto de Astrofisica de Andalucía (CSIC).
