CAESAR Service

CAESAR is a tool for automated source finding in astronomical maps. It allows to extract and parametrize both compact and extended sources from astronomical radio interferometric maps. The processing pipeline is a series of stages that can run on multiple cores and processors.

Compact sources are extracted with flood-fill and blob finder algorithms, processed and fitted using a 2D gaussian mixture model. Extended source search is based on a pre-filtering stage, allowing image denoising, compact source removal and enhancement of diffuse emission, followed by a final segmentation. Different algorithms are available for image filtering and segmentation. The outputs delivered to the user include source fitted and shape parameters, regions and contours.
