# Acknowledging brutifus¶

Only use lower case letters when mentioning brutifus, and always include the release number. Ideally, you should also include a) the DOI associated with any of the Github releases, e.g.:

brutifus 2019.02.2:

brutifus uses several packages that should also be acknowledged in their own right. The following Tex-formatted acknowledgment is one way to do so:

This research has made use of \textsc{brutifus}, a Python module to process data cubes
from integral field spectrographs hosted at \url{http://fpavogt.github.io/brutifus/}.
\textsc{brutus} relies on \textsc{statsmodel} (Seabold & Perktold 2010),
\textsc{matplotlib} (Hunter 2007), \textsc{astropy}, a community-developed core Python
package for Astronomy (Astropy Collaboration et al., 2013, 2018), \textsc{photutils},
an affiliated package of \textsc{astropy} for photometry (DOI:10.5281/zenodo.2533376).


Finally, you also ought to cite the following works, depending on your use of brutifus:

1. Cleveland(1979);

the reference for the Locally Weighted Scatterplot Smoothing (LOWESS) algorithm used by brutus (via statsmodels) to fit the continuum.

2. The reddening laws:

Either the Cardelli, Clayton & Mathis (1989) law, the Calzetti et al. (2000) law or the theoretical model of a turbulent dust screen of Fischera & Dopita (2005) [default] for the extragalactic attenuation corrections, and the Fitzpatrick (1999) law [default] for the galactic extinction.

If you use the extinction values $$A_V$$ and $$A_B$$ from the NASA Extragalactic Database (NED) to correct for the Galactic extinction [default], then to be thorough, you should mention that:

The Galactic extinction is derived using NED from the Schlafly & Finkbeiner
(2011) recalibration of the Schlegel, Finkbeiner & Davis (1998) infrared-based
dust map. The map is based on dust emission from COBE/DIRBE and IRAS/ISSA;
the recalibration assumes a Fitzpatrick (1999) reddening law with Rv = 3.1 and
different source spectrum than Schlegel, Finkbeiner & Davis (1998).


and you also ought to acknowledge NED itself:

This research has made use of the NASA/IPAC Extragalactic Database (NED)
which is operated by the Jet Propulsion Laboratory, California Institute of
Technology, under contract with the National Aeronautics and Space Administration.
