How does it handle physical units in calculations?

It utilizes Astropy's Units and Quantities system, allowing for automatic unit conversion, dimensional analysis, and spectral equivalencies (e.g., wavelength to frequency).

Which cosmological models are available for use?

The skill supports standard built-in models like Planck18 and WMAP, as well as the ability to define custom flat or open Lambda-CDM cosmologies.

Does it support coordinate transformations for Earth-based observers?

Absolutely. It includes support for EarthLocation and AltAz frames, enabling precise local coordinate calculations for specific observatories.

Can this skill handle multi-extension FITS files?

Yes, it provides optimized patterns for reading, creating, and manipulating multi-extension HDU lists within the FITS format.

Are there tools for quick command-line file inspection?

Yes, the skill includes specialized scripts such as fits_info.py and coord_convert.py for rapid data inspection and conversion without writing full Python scripts.
