Member Function Documentation

◆ getBadPixelMask()

def lsst.pipe.tasks.coaddBase.CoaddBaseTask.getBadPixelMask ( self )

Convenience method to provide the bitmask from the mask plane names.

Definition at line 229 of file coaddBase.py.

◆ getCoaddDatasetName()

def lsst.pipe.tasks.coaddBase.CoaddBaseTask.getCoaddDatasetName	(	self,
		warpType = `"direct"`
	)

Return coadd name for given warpType and task config

Parameters
----------
warpType : string
    Either 'direct' or 'psfMatched'

Returns
-------
CoaddDatasetName : `string`

Definition at line 180 of file coaddBase.py.

◆ getSkyInfo()

def lsst.pipe.tasks.coaddBase.CoaddBaseTask.getSkyInfo	(	self,
		patchRef
	)

Use getSkyinfo to return the skyMap, tract and patch information, wcs and the outer bbox of the patch.

Parameters

[in] patchRef data reference for sky map. Must include keys "tract" and "patch"

Returns

pipe_base Struct containing:

skyMap: sky map
tractInfo: information for chosen tract of sky map
patchInfo: information about chosen patch of tract
wcs: WCS of tract
bbox: outer bbox of patch, as an geom Box2I

Definition at line 164 of file coaddBase.py.

◆ getTempExpDatasetName()

def lsst.pipe.tasks.coaddBase.CoaddBaseTask.getTempExpDatasetName	(	self,
		warpType = `"direct"`
	)

Return warp name for given warpType and task config

Parameters
----------
warpType : string
    Either 'direct' or 'psfMatched'

Returns
-------
WarpDatasetName : `string`

Definition at line 194 of file coaddBase.py.

◆ selectExposures()

def lsst.pipe.tasks.coaddBase.CoaddBaseTask.selectExposures	(	self,
		patchRef,
		skyInfo = `None`,
		selectDataList = `[]`
	)

Select exposures to coadd.

Get the corners of the bbox supplied in skyInfo using geom::Box2D and convert the pixel positions of the bbox corners to sky coordinates using skyInfo.wcs.pixelToSky. Use the WcsSelectImagesTask to select exposures that lie inside the patch indicated by the dataRef.

Parameters

[in]	patchRef	data reference for sky map patch. Must include keys "tract", "patch", plus the camera-specific filter key (e.g. "filter" or "band")
[in]	skyInfo	geometry for the patch; output from getSkyInfo

Returns: a list of science exposures to coadd, as butler data references
