Functions

get_pixels_divisions(→ Tuple[int, Ellipsis] | None)

Calculates the Dask Dataframe divisions for a list of HEALPix pixels.

get_pixels_divisions(healpix_pixels: List[hipscat.pixel_math.HealpixPixel]) → Tuple[int, Ellipsis] | None

Calculates the Dask Dataframe divisions for a list of HEALPix pixels.

Divisions include the minimum value of every HEALPix pixel hipscat_id and the maximum value of the last HEALPix pixel hipscat_id. In practice they represent the bounds of hipscat_id values for the target pixels.

Parameters:

healpix_pixels (List[HealpixPixel]) – The list of HEALPix pixels to calculate the hipscat_id bounds for.

Returns:

The Dask Dataframe divisions, as a tuple of integer.
