box_search

Catalog.box_search(ra: tuple[float, float], dec: tuple[float, float], fine: bool = True) → Self

Performs filtering according to right ascension and declination ranges.

The right ascension edges follow great arc circles and the declination edges follow small arc circles.

Filters to points within the region specified in degrees. Filters partitions in the catalog to those that have some overlap with the region.

Parameters:

ratuple[float, float]

The right ascension minimum and maximum values.

dectuple[float, float]

The declination minimum and maximum values.

finebool, default True

True if points are to be filtered, False if not. Defaults to True.

Returns:

Self

A new catalog containing the points filtered to those within the region, and the partitions that have some overlap with it.
