Description
We present a collection of open-source software utilities developed within the Nordic ALMA Regional Centre to support the analysis of radio interferometric data. The tools address crucial aspects of the interferometric workflow, including direct model fitting in the visibility domain, stacking of continuum and spectral-line emission to enhance sensitivity, early data-quality diagnostics using closure quantities and Fourier-space residuals, and simulation and forward-modelling of interferometric observations. Several components are designed to preserve access to the full u-v information beyond standard imaging products, while others provide interactive or educational capabilities to build intuition for aperture synthesis. Although primarily developed for use within the CASA package environment, the methodologies are broadly applicable to interferometric data from facilities other than ALMA. Together, these tools aim to improve robustness, efficiency, and reproducibility in the analysis of interferometric observations across a wide range of science cases.
