Duchamp: A 3D source finder for spectral-line data

Abstract: Duchamp is software designed to find and describe sources in 3-dimensional, spectral-line data cubes. Duchamp has been developed with HI (neutral hydrogen) observations in mind, but is widely applicable to many types of astronomical images. It features efficient source detection and handling methods, noise suppression via smoothing or multi-resolution wavelet reconstruction, and a range of graphical and text-based outputs to allow the user to understand the detections.

Duchamp 1.2 is available now from the link above - there are a few new features and a bunch of bug fixes & improvements to the stability when processing large (>2GB) cubes.

Additionally, the journal paper reference is Whiting (2012), MNRAS 421, 3242, which should be used to cite Duchamp.
