Installation

Conda

SourceXtractor++ is available on Anaconda Cloud for Linux and MacOSX

conda install -c conda-forge -c astrorama sourcextractor==1.0.2

We would recommend, however, to install it into its own environment.

conda create -n sourcex -c astrorama -c conda-forge sourcextractor==1.0.2

conda activate sourcex

Note: If you want the development version to test a future functionality or bugfix, it can also be done with conda:

conda create -n sourcex-dev -c astrorama/label/develop -c astrorama -c conda-forge sourcextractor=x.xx

conda activate sourcex-dev

We recommend always using an explicit version number as there is no guarantee that conda will install the latest version otherwise.

Fedora

SourceXtractor++ is shipped directly in Fedora. It can be installed simply as follows:

sudo dnf install sourcextractor++

We also build our own RPMs as part of our CI setup They can be installed adding a .repo file under /etc/yum.repos.d with the following content:

# Stable and tagged versions
# This is the recommended way to install sourcextractor++
[Astrorama]
name=Astrorama
baseurl=http://repository.astro.unige.ch/euclid/fedora/$releasever/$basearch
enabled=1
gpgcheck=0
 
# Enable this to get the stable (untagged) version
[Astrorama-Stable]
name=Astrorama Stable
baseurl=http://repository.astro.unige.ch/euclid/devel/stable/fedora/$releasever/$basearch
enabled=0
gpgcheck=0
 
# Enable this to get the development version
# Use with care!
[Astrorama-Develop]
name=Astrorama Develop
baseurl=http://repository.astro.unige.ch/euclid/devel/develop/fedora/$releasever/$basearch
enabled=0
gpgcheck=0

And install with

dnf install SourceXtractorPlusPlus

Test Data Set

A test data set covering various data reduction scenarios is available here. It contains the input data, all relevant configuration files, the SourceXtractor++ commands and the expected output results for a reference. The test data set is described as a pre-print for the corresponding conference proceedings.

Discussion group for SourceXtractor++ users

In order to facilitate an active discussion among SourceXtractor++ users we have created a users group. We encourage all users to directly join the group (if a google account is at hand) or to ask us to add you as a member (open an issue on the github page.

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:

Resources for the SourceXtractor++ development are in most part 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.
