About astropy

astropy
Core Python library for astronomy and astrophysics workflows
astropy is an agent skill for astronomy and astrophysics workflows that need the Astropy Python package. Astropy is the core Python library for astronomy, and the skill covers coordinate transformations between systems such as ICRS, Galactic, FK5 and AltAz, unit and quantity calculations, reading and writing FITS image and table files, and cosmological calculations such as luminosity distance, lookback time and the Hubble parameter. It also covers precise time handling across time scales like UTC, TAI, TT and TDB and formats like JD, MJD and ISO. Table work includes reading catalogues, cross-matching, filtering and joining, and the skill covers world coordinate system transformations between pixel and sky coordinates, along with astronomical constants. Use it when a task needs any of these. It is part of the k-dense-ai scientific agent skills repository on GitHub, which has about 49,600 stars. The listing shows it as free, and it has about 1,800 installs. Its security audits show passes from Gen Agent Trust Hub, Socket and Snyk. Install it with npx skills add https://github.com/k-dense-ai/scientific-agent-skills --skill astropy.
