Proceedings ArticleDOI
MAISIE: a multipurpose astronomical instrument simulator environment
TL;DR: The MAISIE project as discussed by the authors is a set of Python classes, interfaces and tools to help build instrument simulators, including imagers and spectrometers, ground and space based instruments.
MAISIE: a Multipurpose Astronomical Instrument SImulator Environment
TL;DR: MAISIE is a simulator framework designed for reuse on different instruments, and has recently been used successfully to develop the simulator for the JWST/MIRI- Medium Resolution Spectrometer.
