STATCONT - A statistical continuum level determination method for line-rich sources
STATCONT is a python-based tool designed to determine the continuum emission level in line-rich spectral data. The tool inspects the intensity distribution of a given spectrum and automatically determines the level by using different statistical approaches. In general, STATCONT has been proved to be accurate at a level < 1% in 50% of the cases, and < 5% in 90% of the cases. The main products are images of the continuum emission level, the error of the determination, and cubes containing only spectral line (i.e. continuum-subtracted cubes).

DataCombination team activities - Interferometer and single-dish data combination
Most of the areas of study in astronomy, such as star formation, the study of extragalactic structures, the evolution of stars and planetary nebulae, depend on high spatial dynamic range observations that can provide information on both the diffuse, extended emission and the dense, more localized emission where astrophysical processes happen. In the last decade, facilities such as the Atacama Large Millimeter/submillimeter Array (ALMA), which hash opened a new window to the study of the 'Cold Universe', aim at providing extremely high fidelity images by combining observations at high-spatial resolution (usually interferometers) with lower-spatial resolution (usually single-dish telescopes) that can recover the extended emission. The DataCombination team aims at testing different methods for the combination of high and low-spatial resolution images, with the goal of providing the community with a guide on how to combine interferometric and single-dish data.
