Pyxel is an open-source python-based framework designed for simulating images including instrumental effects with a strong focus on detector modelling (CCDs & EM-CCDS, CIS, Hybrid-CMOS, APDs, MKIDs etc.). It has been conceived to easily integrate and pipeline models from multiple contributors and in this way foster collaboration in the instrumentation community. The development is led by ESA...

Accurate modeling of detector is essential for precision astronomical measurements and instrument design. We present PyXim, a Python simulation package designed to reproduce the behavior of HxRG CMOS detectors and ASICs at the pixel level, incorporating key noise sources and instrumental effects relevant to image analysis and photometry. The framework models the full signal chain, from photon...
