get_filtered_pixel_list(pixel_tree: hats.pixel_tree.pixel_tree.PixelTree, search_tree: hats.pixel_tree.pixel_tree.PixelTree) → list[hats.pixel_math.HealpixPixel][source]#

Aligns the catalog pixel tree with another pixel tree of interest, and extracts the HEALPix pixels that overlap. This method is useful to obtain the pixels intersecting a pre-defined search space.

Parameters:

  • pixel_tree (PixelTree) – The catalog pixel tree

  • search_tree (PixelTree) – The tree of pixels that defines the search space

Returns:

A list of HEALPix pixels that overlap in both trees.
