How does it handle very large FITS files?

The skill suggests best practices such as memory mapping (memmap=True) and lazy loading to process astronomical data files that exceed available RAM.

Can I use this for complex coordinate transformations?

Absolutely. It provides specific patterns for using SkyCoord, transforming between frames like ICRS and Galactic, and performing efficient catalog matching.

Can it help resolve unit conversion errors?

Yes, it provides troubleshooting for common UnitConversionErrors and demonstrates how to use spectral equivalencies for frequency-to-wavelength conversions.

Does this skill support affiliated packages like Photutils?

Yes, it includes comprehensive guidance for Photutils for aperture and PSF photometry, as well as Specutils for spectroscopic analysis.

Is this skill updated for modern Astropy versions?

Yes, it follows the latest documentation and encourages the use of QTable for unit preservation and Time objects for sub-nanosecond precision.
