Pipe3D, a pipeline to analyse integral field spectroscopy data: II. Analysis sequence and CALIFA dataproducts

TL;DR

Pipe3D is a comprehensive analysis pipeline for integral field spectroscopy data that produces coherent, comparable dataproducts across various surveys and instruments, facilitating studies of stellar populations and ionized gas in galaxies.

Contribution

The paper introduces Pipe3D, a versatile pipeline that standardizes analysis of IFS data, providing publicly available dataproducts and validating the representativeness of properties at galaxy effective radii.

Findings

Successfully derived dataproducts for 200 CALIFA datacubes.

Demonstrated that properties at the effective radius reflect overall galaxy properties.

Made dataproducts freely accessible online.

Abstract

We present Pipe3D, an analysis pipeline based on the FIT3D fitting tool, devel- oped to explore the properties of the stellar populations and ionized gas of Integral Field Spectroscopy data. Pipe3D was created to provide with coherent, simple to distribute, and comparable dataproducts, independently of the origin of the data, focused on the data of the most recent IFU surveys (e.g., CALIFA, MaNGA, and SAMI), and the last generation IFS instruments (e.g., MUSE). Along this article we describe the different steps involved in the analysis of the data, illustrating them by showing the dataproducts derived for NGC 2916, observed by CALIFA and P-MaNGA. As a practical use of the pipeline we present the complete set of dataproducts derived for the 200 datacubes that comprises the V500 setup of the CALIFA Data Release 2 (DR2), making them freely available through the network (ftp://ftp.caha.es/CALIFA/dataproducts/DR2/Pipe3D). Finally, we explore the hypothesis that the properties of the stellar populations and ionized gas of galaxies at the effective radius are representative of the overall average ones, finding that this is indeed the case.
