Introduction:
GrISU(tah)
is a package of programs for simulating the development of amospheric showers
and telescope response to atmospheric shower Cherenkov fronts. The package
also contains a data analysis program to process the data generated by the
detector model. Because the development of GrISU started in the context
of the VERITAS experiment,
the package also contains tools for analysing and displaying VERITAS data
as well as VERITAS specific configuration files.

The package is currently maintained by
Charlie Duke (CD) and Stephan LeBohec (SLB). It is made up of 5 main programs
of different origins:
Distribution and Feedback:
- The shower development simulation
program used in GrISU is an older version of the kascade program taken from
the ISUSim package. CD made numerous changes in the I/O and we now refer
to it as kascade7. Glenn Sembroski (Purdue University) and Mary Kertzman
(DePauw University) originally developed the kascade code.Glenn Sembroski and Mary Kertzman's most recent
version compiles under Absoft-F77 and is thus VMS compatible. It is the
most developed and updated of all kascade version and it is now included in this package.
- The Cherenkov light emission and propagation program (cherenk) was developed at ISU by David Carter-Lewis and Gora Mohanty. CD introduced the timing and implemented the control interface.
- The detector simulation program
(grisudet) was developed by CD and SLB. The program structure and some hardware
models are inspired from SLB's earlier work on the CAT imaging telescope.
- The analysis program (analysis) was developed by CD and SLB.
- The final product analysis program (datareader) was developed by Pierre Colin and SLB.
