The code was derived from the 1-dimensional SimLine program. Combining two approximations for the radiative coupling between remote points, it allows to simulate the line radiation from turbulent media. A full description can be found in Ossenkopf (2002).
I have written several programs on the coagulation and optical properties of dust particles during my PhD studies in Jena. They are written in FORTRAN 77 and partially require the SUN or Mongo graphics library.
We improved the Delta-variance method introduced by Stutzki et al. (1998) to be applicable to data sets with irregular boundaries and variable significance of the individual data points. The algorithm is described in Ossenkopf, Krips & Stutzki (2008a) and its application is demonstrated in Ossenkopf, Krips & Stutzki (2008b). The IDL code provided here performs the Delta-variance analysis for arbitrary FITS files providing all options discussed in the papers.
We introduced an anisotropic wavelet analysis to characterise filamentary structures in the interstellar medium. The method has been described and extensively tested in Ossenkopf-Okada & Stepanov (2019) where we have also applied it to observed maps. An extended version including more options for the edge treatement and the significance weighting of individual points in astronomical maps is provided here as IDL code. Start with the demo.pro script to understand the usage.
For my lecture series ``Chaos und Struktur in nichtlinearen Systemen'' I have written a number of flexible and comfortable tools to study and demonstrate the behaviour of nonlinear systems. They range from one-dimensional iteration systems to examples like the driven pendulum.
This is program intended for public outreach purposes to demonstrate the fractal properties of many natural phenomena. It generates fractal sounds, landscapes, and interstellar clouds. Documentation is available in German only.
In the process of testing and calibrating the HIFI instrument a large set of user scripts for the comfortable handling of HIFI data have been developed. They entered the official Herschel Common Software System and are updated in the regular system builds.
From 1995-2006 I was active as Debian package maintainer, being responsible for the packages workman and xvmount. By now they have been removed from the distribution. If you are interested in the last code version you can find it in the FTP directory.
This is a CGI script to scan the archive and the CD-ROM full text version of the German computer magazine c't. The latest version is suitable for all CDs from 1990 to 2010. For newer versions of the CD-ROM, only the archive can be scanned. The README file explaines some of its features and the CHANGES file shows how they were added from version to version.
