LEDAS Software Distribution
The distribution of simulation software, software for X-ray data analysis
and proposal preparation tools is a relatively new but growing service provided
by LEDAS. Users in the UK should find using our mirror sites faster and
more convenient than downloading the files from the USA directly.
Ginga
Analysis Software:
|
Leicester played a major part in the development
of the Ginga data analysis software, and LEDAS
maintains a full archive of the downloadable software and supporting
documentation.
This software package is used to reduce raw Ginga data
'from scratch' and requires some familiarity with Ginga
to use properly. Less experienced users may find the partly-reduced
contents of the data archive easier to work with.
|
PIMMS:
|
PIMMS (Portable, Interactive, Multi-Mission
Simulator) is intended as a versatile simulation tool for X-ray
astronomers. With PIMMS one can find the expected count rate
from most X-ray astronomy instruments based upon the detected
flux from another detector. This conversion is achieved by specifying
an input spectral model which is extrapolated from the input
spectral range to the output.
LEDAS also provides a copy of WebPIMMS,
the on-line version of PIMMS.
|
| PROFIT: |
Profit is a GUI (graphical user interface)
tool for accessing high-resolution spectra. Profit displays
spectra in various formats, allowing users to identify emission
lines, to convert an identified line into velocity units using
a user-selected wavelength, to store (and restore) individual
spectra, to fit lines to gaussians, and other features. Profit
primarily handles the "exploratory" phase of analysis,
although it has some powerful features.

HEAsoft
software suite:
|
| HEAsoft
is a software suite in which the FTOOLS and XANADU software
packages have been merged. The packages are integrated so
that they share common libraries and build procedures, greatly
improving compatibility. FTOOLS and XANADU can be downloaded
and installed together or separately.
This is a mirror of
the original HEAsoft site at HEASARC
which provides access to the downloadable source codes, binary
executables and supporting on-line documentation.
|
Chandra
software:
|
LEDAS holds a copy of the package of software
for Chandra data analysis, called "CIAO" (Chandra Interactive
Analysis of Observations), as released by the Chandra X-ray
Observatory Center (CXC) at CfA Harvard. The full distribution
can be downloaded (by ftp) from the CIAO
download page on the Chandra Website mirror.
There are also extensive supporting
notes available on the mirror.
|
| Opacity Project: |
The Opacity Project is an
international collaboration formed to calculate the atomic data
required to estimate stellar envelope opacities, and to compute
Rosseland mean opacities and other related quantities.
Complete data and codes for computing Rosseland mean opacities
and radiative accelerations are available for download. This
is a mirror of the Opacity Project download page at ViZieR.

| Links to all of these packages are provided
in the left-hand sidebar. We are keen to incorporate more of the
software that UK astronomers wish to use. If there is a software package that
you would like to see available here, please let us know. Our contact e-mail address
is at the bottom of the sidebar.
