References and Acknowledgment

While we are working on several refereed papers describing SourceXtractor++ and its software architecture, the software package can be referenced with two ADASS conference proceedings:

• Bertin, E.; Schefer, M. ; Apostolakos, N. ; Álvarez-Ayllón, A.; Dubath, P. ; Kümmel, M.: 2020ASPC..527..461B

The ressources for the SourceXtractor++ development are mostly provided by funding from the Euclid satellite project via the various national agencies. For Euclid Consortium papers it is sufficient to point to the SourceXtractor++ webpage and add the standard EC acknowledgement text.

For scientific publication which are non EC papers we would be greatful if the following acknowledgment could be added:

This research made use of {\tt SourceXtractor++}\footnote{https://github.com/astrorama/SourceXtractorPlusPlus},
an open source software package developed for the Euclid satellite project.
