Function Documentation

◆ find_region_for_detector()

lsst.pipe.tasks.extended_psf.find_region_for_detector ( detector_id,
detectors_focal_plane_regions )
Find the focal plane region that contains a given detector.

Parameters
----------
detector_id : `int`
    The detector ID.

detectors_focal_plane_regions :
        `dict` [`str`, `lsst.pipe.tasks.extended_psf.DetectorsInRegion`]
    A dictionary containing focal plane region names as keys, and the
    corresponding detector IDs encoded within the values.

Returns
-------
key: `str`
    The name of the region to which the given detector belongs.

Raises
------
KeyError
    Raised if the given detector is not included in any focal plane region.
