The sherpa.astro.instrument module

Models of common Astronomical models, particularly in X-rays.

The models in this module include support for instrument models that describe how X-ray photons are converted to measurable properties, such as Pulse-Height Amplitudes (PHA) or Pulse-Invariant channels. These ‘responses’ are assumed to follow OGIP standards, such as [1].
