The radiation environment outside the Earth’s magnetosphere is an issue for most space-based detectors. Highly energetic particles from the Sun can damage Charge-Coupled Devices (CCDs) by creating defects in their silicon lattice. These defects are able to trap electrons during the read out of the CCD and thus create a smearing effect that is detrimental to the scientific data.

The constructive and destructive interference of infrared light in detector arrays, used in both ground-based and space-based infrared astronomical instruments, is a complex and impactful systematic to characterise. For broadband imaging the interference can enlarge the instrument point spread function significantly, while for medium-to-high resolution spectroscopy it can introduce a large...
HxRGprocc is a general open source tool we built to simulate as well as reduce HxRG up-the-ramp data. In this talk, I shall mainly focus on the empirical models we developed to fit the pixel by pixel non-linearity curves of the H2RG detector pixels in the Habitable zone Planet finder spectrograph which uses a 1.7 micron H2RG detector. I shall also talk about the other features in HxRGprocc,...
