astropy

You can convert celestial coordinates from ICRS to Galactic using astropy.coordinates. It provides SkyCoord objects that enable seamless transformations between different astronomical coordinate systems with built-in unit handling.

The best way to handle FITS files is using astropy.io.fits. It provides a unified Python interface for reading, writing, and manipulating FITS file data, integrating seamlessly with other astronomical data analysis tasks like coordinate transformations and table operations.

You compute luminosity distance using astropy.cosmology with Planck18 parameters. It allows you to calculate distances at specific redshifts, such as z=1, by providing built-in cosmological models and distance calculation functions for your astronomical research pipelines.

Yes, astropy supports World Coordinate System transformations through astropy.wcs. It enables you to transform pixel coordinates to sky coordinates and vice versa, integrating with FITS file handling and celestial coordinate systems for comprehensive image analysis workflows.

Yes, you can manage astronomical time formats using astropy.time and physical units with astropy.units. This unified toolkit provides consistent array support and unit handling across time computations, coordinate transformations, and cosmology calculations within cohesive analysis pipelines.

Astropy unifies astronomical catalogs, images, and simulations workflows into a single Python toolkit. It provides module-level APIs for coordinate transformations, FITS file I/O, cosmology calculations, and WCS transformations, enabling researchers to build cohesive multi-module data analysis pipelines.
