What kind of data might TRIPP be useful for?

It was originally designed for the reduction of CCD data from WET runs, and its principal purpose is to extract lightcurves from such data. It is therefore optimized for automatic handling of large numbers of CCD frames that are identical to each other with respect to their binning, approximate windowing, and approximate location of the sources on the subframes, and that follow a naming scheme for the data files which systematically numbers subsequent frames. TRIPP may also be used with more inhomogeneous data sets, which however will require some more thinking on the side of the user. In addition to the data reduction procedures, TRIPP also offers tools for a subsequent manipulation and analysis of the resulting lightcurve(s).

Technical requirements for running TRIPP

TRIPP is software written in the IDL language, based on the CCD photometry package and other components in the aitlib. These in turn are partly based on the IDLPHOT routines, but also use other routines from the IDL Astrolib. TRIPP will not work if any one of these components is missing! To avoid problems related to the usage of the aitlib, we currently provide a TRIPP package for download that includes all aitlib routines needed, so you just need to make sure that the astrolib is available. Please also note that some basic knowledge of IDL will be very helpful if you want to use this package.
TRIPP has only been developed and tested on UNIX-type OSes and will probably not run on other platforms.


Please keep in mind that the software itself is under constant development (the analysis of combined data sets is the most severly affected section at the moment).
The software is provided "as-is" and without warranty of any kind, express, implied or otherwise, including without limitation, any warranty of merchantability or fitness for a particular purpose.

If you have used TRIPP in your research or have used data in your research that has been analysed with TRIPP, we would welcome the inclusion the following reference in your corresponding publication:

If you wish to use this software, please contact us.
  • aitlib.tar.gz [379k]
    Includes all the TRIPP and SPEX routines and the content of several other directories in the aitlib that TRIPP or SPEX may need. All of the aitlib files, including the TRIPP and SPEX files, though taken from different directories, will unpack together and directly into the directory where you do the untarring. The only other library needed, the astrolib, is NOT included (get astrolib here). The aitlib.tar.gz file provided here is the latest available screenshot of the CVS repository.
  • Older versions of TRIPP
  • Tools for observing at Calar Alto

The entries for individual routines may also be accessed via the headings in the Users' Manual.
The cvsweb pages formerly also hosted in Tübingen are no longer available.
The development version of TRIPP resides in the Göttingen subversion repository since early 2005. Not publicly available. If you've been put on the development team there, learn how to use Subversion to read the changelogs etc.


TRIPP is based on routines by Ralf D. Geckeler and has since 1999 been developed and repeatedly extended by Sonja Schuh and Stefan Dreizler, who acknowledge contributions from Jochen Deetjen (original design of the transition from CCD to TRIPP), Thomas Gleissner (handling of different image sizes), Patrick Risse (new FITS keywords), Thomas Rauch (new FITS keywords), Eckart Göhler (new graphics of mask definition, new positioning, various bug fixes), Simon Hügelmeyer (dark correction), Tim-Oliver Husser (new positioning) and Holger Israel (difference imaging). The time series analysis parts draw on work by Sara Benlloch-Garcia, Katja Pottschmidt and Jörn Wilms.
