Introduction
PIMMS (Portable, Interactive, Multi-Mission Simulator) is intended
as a versatile simulation tool for X-ray astronomers.
PIMMS uses one command GO for actual execution, while
other commands are mostly used for setting up various parameters. This
approach allows users to repeat similar calculations using a slightly
different parameter.
PIMMS uses the following terms:
- Model: spectral model to be used. PIMMS contains a
small set of simple spectral models, and others can be imported.
- However, spectral simulation is not a strength of PIMMS
- it does not output spectra as such, and it is unlikely that
PIMMS can keep up with the multitude of models that are
used for various types of objects. We recommend
the use of XSPEC for a full spectral simulation.
- Instrument: in addition to the instrument for which simulation is
to be done, you can also specify the input instrument
for count rate calculations.
This is used for calculating normalization of the model; rather than
starting from the source flux in cgs unit, PIMMS can start from e.g.,
Einstein IPC count rate.
