PIMMS v4.8f now available
Version 4.8f contains an updated set of Chandra effective area curve
files, suitable for use for Cycle 20 proposals. If you already
have version 4.8 installed, you can simply download
and unpack its content on the data subdirectory of your PIMMS
installation - the existing executable will automatically pick up the new

Command-line tool and the Web interface
PIMMS was originally written as a stand-alone,
interactive program (the "command line PIMMS").
implements a subset of the functionalities of the command line
PIMMS. While allowing easy access, without the need to
install the software, it does not have all the functionality
of the command line version.
PIMMS, as described here, is software for high-energy
astrophysicists, and has nothing to do with
the Project to Increase Mastery of Mathematics and Science.
The program was named quite independently of this
worthwhile project at Wesleyan University.
Time-Variable Instrumental Response
PIMMS currently does not support time-variable calibration
of instruments. Because it is primarily intended as a planning tool
for future observations, the responses in PIMMS is often
applicable for upcoming observations.
For example, if you are a Chandra user who wishes
to convert count rates in a past observation to flux, please see
PIMMS is currently supported on several flavors of UNIX
workstations, on Linux PCs, Macs running OS X/Darwin.
It requires a Fortran compiler, and make on UNIX machines.

Adding new missions and other future plans
At a very basic level, new missions can be added simply by
creating a set of effective area curve files: they need to
be two-column ASCII files, containing pairs of photon energy
in keV and effective area in cm2.
PIMMS source code and data files are distributed
freely, without restrictions. If you decide to add new
missions to PIMMS, we would like to be able to distribute
it from HEASARC.
We hope to have a programmers' guide some day to make it easier
to add mission-specific information.
Credits and Feedback
PIMMS is mostly written and maintained by Koji Mukai.
Effective area curves for current and future missions have been supplied
by the respective projects. XTE specific subroutines have been written
by Koji Mukai, with the help of Jim Lochner and Phil Blanco. The SAX
specific subroutine has been written by the SAX Data Center and
Lorella Angelini. Snowden R-band effective area curves for ROSAT
PSPC have been created by Richard West of Leicester.
The only published article on PIMMS is in the HEASARC journal:
Mukai, K. 1993, Legacy 3, 21-31.
