Stingray: Next-Generation Spectral Timing

Stingray is a community-developed astrophysical spectral-timing software package written in Python.

There are a number of official software packages for X-ray spectral fitting (XSPEC, ISIS, Sherpa, …). Such a widely used and standard software package does not exist for X-ray timing, so until now it has mainly been the domain of custom, proprietary software. Stingray originated during the 2016 workshop The X-ray Spectral-Timing Revolution: a group of X-ray astronomers and developers decided to agree on a common platform to develop a new software package. The goals were to merge existing efforts towards a timing package in Python, following the best guidelines for modern open-source programming, thereby providing the basis for developing spectral-timing analysis tools. This software provides an easily accessible scripting interface (possibly a GUI) and an API for power users. Stingray’s ultimate goal is to provide the community with a package that eases the learning curve for advanced spectral-timing techniques, with a correct statistical framework.

Further spectral-timing functionality, in particularly command line scripts based on the API defined within Stingray, is available in the package HENDRICS. A graphical user interface is under development as part of the project DAVE.
