Python

AI Summary: Rewrite the `cone_filter` function in the LSDB Python package to improve performance by replacing the existing Astropy-based coordinate separation calculation with a NumPy-based implementation using the great circle arc length formula. This aims to achieve approximately a 2x speedup. The provided code snippet offers a potential implementation.

Complexity: 4/5

AI Summary: Implement case-insensitive column name handling for 'RA' and 'DEC' in the `lsdb.from_dataframe` function. This involves modifying the function to accept variations in capitalization (e.g., 'ra', 'Ra', 'RA', 'dec', 'Dec', 'DEC') for the right ascension and declination columns when creating an LSDB object from a Pandas DataFrame.
