Pyhdust provides analysis and visualization tools for multi-technique stellar observations and for working with hdust models, with emphasis on Be-star applications. It reads and manipulates hdust outputs and includes modules for spectroscopy, polarimetry, and optical/IR interferometry. Pyhdust includes additional routines that cover photometric filters, image utilities, rotating-star and single-scattering calculations, Be-star quantity conversions, and BeAtlas helpers for grid/model handling.
