PolygonSearch

class PolygonSearch(vertices: list[tuple[float, float]], fine: bool = True)

Perform a polygonal search to filter the catalog.

IMPORTANT: Requires additional lsst-sphgeom package

Filters to points within the polygonal region specified in ra and dec, in degrees. Filters partitions in the catalog to those that have some overlap with the region.

Methods

filter_hc_catalog(hc_structure)	Determine the target partitions for further filtering.
perform_hc_catalog_filter(hc_structure)	Filters catalog pixels according to the provided pixel set
plot([projection, title, fov, center, wcs, ...])	Plot the search region
search_points(frame, metadata)	Determine the search results within a data frame

__init__(vertices: list[tuple[float, float]], fine: bool = True)

Methods

__init__(vertices[, fine])
filter_hc_catalog(hc_structure)	Determine the target partitions for further filtering.
perform_hc_catalog_filter(hc_structure)	Filters catalog pixels according to the provided pixel set
plot([projection, title, fov, center, wcs, ...])	Plot the search region
search_points(frame, metadata)	Determine the search results within a data frame
