Does it support FITS file manipulation?

Absolutely. It provides patterns for reading, writing, and modifying FITS headers and both image and table HDU data using context managers.

Is it useful for catalog cross-matching?

Yes, it provides efficient methods for matching sky coordinates and performing database-style joins on large astronomical tables.

Can I use it for cosmological research?

Yes, it includes guidance for using built-in models like Planck18 and WMAP9 to calculate distances, ages, and Hubble parameters at specific redshifts.

How does it handle physical units?

It utilizes the astropy.units framework to ensure dimensional consistency and facilitate easy conversion between astronomical units like parsecs, Janskys, and magnitudes.

Can this skill help with coordinate transformations?

Yes, it supports converting between systems like ICRS, Galactic, FK5, and AltAz, including observer-dependent frames requiring specific time and location data.
