NuSTAR Code

Background Modeling Software: nuskybgd

The NuSTAR telescope has an open optical path between its mirrors and detectors, allowing unreflected X-rays to shine directly on the focal plane, producing an additional background with a spatial gradient. This feature makes the standard procedure for dealing with the background -- characterizing the background in a blank location within the field of view -- incorrect. The nuskybgd code allows the user to model its contribution to the background along with that from instrumental, focused cosmic, and sunlight-induced background components. It can be retrieved here from github, and a description of how it works can be found in this paper.

Spatial-Spectral Fitting: nuskycube

Originally conceived to treat NuSTAR data as a three dimensional datacube (x,y,E) to be simultaneously fit spatially and spectrally, in practice the method is too computational intensive. The software exists in a few similar forms, adapted to specific datasets, and focuses on performing spatial fits in several energy bands simultaneously. This approach is necessitated by NuSTAR's broad point spread function. The software is currently under final development with the aim of public release.

Other Analysis Code

Largely centered around the spatial analysis of diffuse emission, I have various other bits of code, mostly written for Chandra and/or XMM-Newton data. Hope to clean it up one day and make public, but not this day.
