  ScopeSim is a flexible multipurpose instrument data simulation framework
built in Python.
  It enables both raw and reduced observation data to be simulated for a wide
range of telescopes and instruments quickly and efficiently on a personal
computer. The software is currently being used to generate simulated raw input
data for developing the data reduction pipelines for the MICADO and METIS
instruments at the ELT. The ScopeSim environment consists of three main
packages which are responsible for providing on-sky target templates
(ScopeSim_templates), the data to build the optical models of various
telescopes and instruments (instrument reference database), and the simulation
engine (ScopeSim). This strict division of responsibilities allows ScopeSim to
be used to simulate observation data for many different instrument and
telescope configurations for both imaging and spectroscopic instruments.
ScopeSim has been built to avoid redundant calculations wherever possible. As
such it is able to deliver simulated observations on time scales of seconds to
minutes. All the code and data is open source and hosted on Github. The
community is also most welcome, and indeed encouraged to contribute to code
ideas, target templates, and instrument packages.
