Why make Stingray? A.L. Stevens Ÿ U. Amsterdam Ÿ @abigailStev Image: XKCD 

Why make Stingray? — Not much public X-ray timing code Legacy code, “black box” — No public X-ray spectral-timing code Public code = anyone can read source code, code is well-documented A.L. Stevens Ÿ U. Amsterdam Ÿ @abigailStev 

Why open-source? A.L. Stevens Ÿ U. Amsterdam Ÿ @abigailStev — Reproducibility — Transparency — Reusability — Transfer to other fields? Image: GitHub 

Why Python? Slide adapted from J. VanderPlas SciPy PyMC A.L. Stevens Ÿ U. Amsterdam Ÿ @abigailStev 

Stingray + HENDRICS + DAVE Python application programming interface Shell script interface Graphical user interface A.L. Stevens Ÿ U. Amsterdam Ÿ @abigailStev + tutorials in Jupyter notebooks 

—  Library of time series analysis methods —  Power spectra, cross spectra, bispectra —  Lag-frequency & lag-energy spectra —  Rms & covariance spectra —  Coherence, cross-correlation —  Handles GTIs, pulsar & QPO searches —  Simulator, modeling Leads: D.
