HealSparseInputMapTask

class lsst.pipe.tasks.healSparseMapping.HealSparseInputMapTask(**kwargs)

Bases: Task

Task for making a HealSparse input map.

Methods Summary

build_ccd_input_map(bbox, wcs, ccds)	Build a map from ccd valid polygons or bounding boxes.
finalize_ccd_input_map_mask()	Use accumulated mask information to finalize the masking of ccd_input_map.
mask_warp_bbox(bbox, visit, mask, bit_mask_value)	Mask a subregion from a visit.

Methods Documentation

build_ccd_input_map(bbox, wcs, ccds)

Build a map from ccd valid polygons or bounding boxes.

Parameters

bboxlsst.geom.Box2I

Bounding box for region to build input map.

wcslsst.afw.geom.SkyWcs

WCS object for region to build input map.

ccdslsst.afw.table.ExposureCatalog

Exposure catalog with ccd data from coadd inputs.

finalize_ccd_input_map_mask()

Use accumulated mask information to finalize the masking of ccd_input_map.

Raises

RuntimeError : Raised if build_ccd_input_map was not run first.

mask_warp_bbox(bbox, visit, mask, bit_mask_value)

Mask a subregion from a visit. This must be run after build_ccd_input_map initializes the overall map.

Parameters

bboxlsst.geom.Box2I

Bounding box from region to mask.

visitint

Visit number corresponding to warp with mask.

masklsst.afw.image.MaskX

Mask plane from warp exposure.

bit_mask_valueint

Bit mask to check for bad pixels.

Raises

RuntimeError : Raised if build_ccd_input_map was not run first.
