The GIST Pipeline: A Multi-Purpose Tool for the Analysis and Visualisation of (Integral-field) Spectroscopic Data

We introduce a convenient, all-in-one framework for the analysis of IFS data. The GIST conducts all steps from read-in and preparation of data, over the analysis, to the production of publication-quality plots. In its basic setup, it extracts stellar kinematics, performs an emission-line analysis and derives stellar population properties from full spectral fitting as well as via the measurement of line-strength indices. To this end, the pipeline uses the well-known pPXF and GandALF routines, while being fully independent of the used instrument and employing an elaborate parallelisation. GIST further features a dedicated visualization routine with a sophisticated graphical user interface. This routine allows easy access of all measurements, spectra, fits, and residuals in fully-interactive plots. The pipeline is already used by numerous surveys, such as TIMER, Fornax3D, PHANGS, and WEAVE.
