   The GIST Framework: A multi-purpose tool for the analysis and visualisation of (integral-field) spectroscopic data
========================================================================================================================

The GIST is a convenient, all-in-one framework for the scientific analysis of fully reduced, (integral-field)
spectroscopic data. It is entirely written in Python3 and conducts all steps from the preparation of input data, over
the scientific analysis to the production of publication-quality plots.

In its default implementation, it extracts stellar kinematics, performs an emission-line analysis, derives star
formation histories and stellar population properties from full spectral fitting as well as via the measurement of
absorption line-strength indices. To this end, the GIST is exploiting the well-known pPXF and GandALF routines. In
addition, the framework is not specific to any instrument or analysis technique and provides easy means of modification
and further development, as of its modular code architecture. In fact, it is not only a neat combination of already
existing fitting routines, but a fully modular framework for the analysis of spectroscopic data in the context of a
variety of scientific objectives. 

The software further features the dedicated visualisation routine Mapviewer which has a sophisticated graphical user
interface. This allows the easy, fully-interactive plotting of all measurements, in particular maps, observed spectra,
fits, residuals, as well as star formation histories and the weight distribution of the models. 

An elaborate, Python-native parallelisation is implemented and tested on various machines from laptop to cluster scales. 

To date, the GIST framework has successfully been applied to both low and high-redshift data from MUSE, PPAK (CALIFA),
SINFONI, KCWI, and MaNGA, as well as to simulated data for HARMONI, WEAVE, and other artificial observations.

Citing GIST and the analysis routines
-------------------------------------
If you use this software framework for any publication, please cite Bittner et al. 2019 (A&A, 628, A117;
https://ui.adsabs.harvard.edu/abs/2019A%26A...628A.117B) and include its ASCL entry (http://ascl.net/1907.025) in a
footnote. 

We remind the user to also cite the papers of the underlying analysis techniques and models, if these are used in the
analysis. In the default GIST implementation, these are the adaptive Voronoi tesselation routine (Cappellari & Copin
2003), the penalised pixel-fitting method (pPXF; Cappellari & Emsellem 2004; Cappellari 2017), the pyGandALF routine
(Sarzi et al. 2006; Falcon-Barroso et al. 2006; Bittner et al. 2019), the line-strength measurement routines (Kuntschner
et al. 2006; Martin-Navarro et al. 2018), and the MILES models included in the tutorial (Vazdekis et al. 2010). 


Disclaimer
----------
Although we provide this software as a convenient, all-in-one framework for the analysis of integral-field spectroscopic
data, it is of fundamental importance that the user understands exactly how the involved analysis methods work. We warn
that the improper use of any of these analysis methods, whether executed within the framework of the GIST or not, will
likely result in spurious or erroneous results and their proper use is solely the responsibility of the user. Likewise,
the user should be fully aware of the properties of the input data before intending to derive high-level data products.
Therefore, this software framework should not be simply adopted as a black-box. To this extend, we urge any user to get
familiar with both the input data and analysis methods, as well as their implementation.
