The images include a complex fluctuating backgroundĬloud, a long dense filament, and many starless and protostellar cores. Methods to enable the selection of the most reliable and accurate method. These pages describe a realistic multi-wavelength set of benchmark images for testing and comparing source and filament extraction
Structures to extract, that users have to determine from the input images on the basis of their research interests. This almost universal and fully automated method has a single user-definable parameter, the maximum size of the Getsf measures the detected sources and filaments and creates the output catalogsĪnd images. It spatially decomposes theįlattened components, combines them over wavelengths, and detects the positions of sources and skeletons of filaments. Sources and filaments from each other and from their backgrounds, flattening their resulting images. The method spatially decomposes the original images and separates the structural components of These pages present getsf, a new method for extracting sources and filaments inĪstronomical images using separation of their structural components, designed to handle multi-wavelength sets of images and veryĬomplex filamentary backgrounds.
Qualities highlights the need to use standard benchmarks for choosing the most reliable and accurate method for the astrophysical Availability of uncalibrated extraction tools with widely varying Complexįluctuating backgrounds and filamentary structures appear differently on various scales, calling for multi-scale approaches forĬomplete and reliable detection of sources and filaments. Resolutions across wavebands require extraction tools that preserve and use the invaluable high-resolution information. The multi-wavelength observations with highly variable angular Information about the complex physical processes in space. Their analysis and accurate extraction of sources, filaments, and other structures, containing massive amounts of detailed
