User guide for the DTFE code

There is an extensive PDF document that serves as the documentation for the DTFE program. This document describes everything from the installation process, to the program options and several examples of using the software.

The documentation for the DTFE program comes in the same archive as the source code itself, so you don't need to download it separately. In case you wish to obtain only the latest version of the documentation (without having to download the rest of the archive), than download it from here (size 2MB).

The DTFE method scientific papers:

  • Schaap, W. E. & van de Weygaert, R. 2000, Astronomy and Astrophysics, 363, L29 - ADS link - the letter describing the original idea of using Delaunay tessellation for field reconstruction.

  • Schaap, W. PhD thesis "DTFE: the Delaunay Tessellation Field Estimator" - link - Schaap's PhD thesis: describes the DTFE method and compares the DTFE results with SPH and other field reconstruction methods.

  • van de Weygaert, R. & Schaap, W. 2009, 665, 291 - ADS link, arXiv link - lecture notes on the DTFE method and its application in studying large scale structure.

  • Cautun, M. & van de Weygaert, R., "The DTFE public software" - link - gives and overview of the DTFE software.

  • Cautun, M., Schaap, W., & van de Weygaert, R. 2011, M.N.R.A.S., in prep. - the complete and updated DTFE procedure on which this public code is based.


The authors acknowledges the work of Erwin Platen who wrote a basic version of the DTFE density interpolation code which was used as the starting point of this work. I am also grateful for discussions with Patrick Bos, Pratyush Pranav, Miguel Aragon-Calvo and Johan Hidding whose suggestions shaped the form and features of the software. I am also grateful to Monique Teilland, Manuel Caroli and Gert Vegter for their work in developing the CGAL library as well as their help and support with the CGAL library. We thank Willem Schaap for his work in developing the DTFE method as a mature analysis tool for studying cosmological data. A special acknowledgment goes to Bernard Jones, whose continuing involvement and encouragement during the various stages of DTFE development have been instrumental.
