Welcome to the IUE Calibration and Utilities Software page.
All the spectral images obtained by the International Ultraviolet
Explorer have been recalibrated by the NASA/ESA IUE Project
using the NEWSIPS calibration pipeline. The NEWSIPS software is currently
being ported to the IRAF environment to allow users to recalibrate their
images with certain custom processing options that may be more appropriate
for their science.
The NEWSIPS pipeline is included in an IRAF layered package called
iue. General information about the
iue package can be found below, but the project to port NEWSIPS also
includes providing certain utilities and documentation to facilitate
analysis of IUE data with existing IRAF, TABLES, and STSDAS tasks.
Obtaining the Software
IUE External Package
The iue package, which includes the NEWSIPS pipeline, is currently
in alpha-testing, and a public release is planned in the near future. Some of
the utilities, including data format conversion tasks, are offered in a
package called iuetools. This small package is available
independently for personal installation (see description below).
The following resources will be offered from the
ftp distribution area
when the full newsips package is released:
-
tar of source files
- User Guide
& Installation Manual
-
Calibration reference files
IUETOOLS Personal Package
 New
Version (V1.1)
The current version, V1.1, was released on 9-Aug-1999. This version
corrects a bug in the "mxexpand" task, and eliminates the dependence in
V1.0 on the STSDAS package. For further details, see the package release notes.
Current users of this package are encouraged to upgrade.
The subset package, called iuetools is available separately from the
iue external package (see above) for personal installation. This
package includes two utilities for converting the archived files containing
the extracted spectra (.mxlo or .mxhi files) to formats compatible with
various STSDAS and IRAF tasks, such as igi and splot.
There is also a utility for generating a short summary of the file headers.
The following resources can be obtained from the
ftp distribution area:
System Requirements
Both the iue and iuetools packages depend upon the following
software:
Both of these packages must be installed and properly configured on your
system in order for the software offered here to install and work correctly.
Contributed Software
IRAF users who analyze IUE data occasionally write CL scripts or
small compiled tasks for special analysis purposes. As a courtesy to these
authors and to further support in IRAF for the IUE community, we are
making such contributed
software available from the NEWSIPS ftp site. Please note that
the responsibility for the use, support, and maintenance of contributed
software rests with the authors.
The NEWSIPS calibration software was originally developed for the
IUE Observatory Final Archive. This iue package,
including the port of the NEWSIPS pipeline, is being developed by
Richard A. Shaw and Howard A. Bushouse (Space Telescope Science
Institute). Our goal is to offer to the community a pipeline which
reproduces to good accuracy the calibrated products in the IUE
final archive when given the same input parameters, but which provides
additional, custom processing options to enable users to optimize the
science from their particular programs.
A paper describing the scope of this package by
Shaw & Bushouse is available in the ADASS VII proceedings:
1998, ASP Conf. Ser., Vol. 145,
Astronomical Data Analysis Software and Systems VII, ed. R. Albrecht,
R. N. Hook, & H. Bushouse (San Francisco: ASP), 103; a
reprint of this paper is available in PDF format.
This project is funded by the NASA Astrophysics Data Program through grant
NAG5-32697 to Space Telescope Science Institute.
