ISIS Home Page

ISIS, the Interactive Spectral Interpretation System, is designed to facilitate the interpretation and analysis of high resolution X-ray spectra. It is being developed as a programmable, interactive tool for studying the physics of X-ray spectrum formation, supporting measurement and identification of spectral features, and interaction with a database of atomic structure parameters and plasma emission models.

One of the most powerful features of ISIS is its programmability. By writing S-Lang scripts that use ISIS functions, you can

Automate repetitive data analysis tasks.
Do array calculations directly in memory, without generating intermediate FITS files.
Directly read and write custom FITS binary tables.
Easily generate custom plots using an interpreted interface to the PGPLOT subroutine library.
Control standard command-line software such as FTOOLS and Ciao
Fit user-defined models coded in S-Lang, C, C++ or Fortran
Incorporate external C, C++, or Fortran codes into your ISIS analysis, either by hand or automatically with the SLIRP vectorizing code generator.
With the PVM module, distribute computationally expensive tasks across a network of workstations (for example, confidence limits and model evaluation)

See the features page for more information.
