Detailed Description

Select images using their Wcs

    We use the "convexHull" method of lsst.sphgeom.ConvexPolygon to define
    polygons on the celestial sphere, and test the polygon of the
    patch for overlap with the polygon of the image.

    We use "convexHull" instead of generating a ConvexPolygon
    directly because the standard for the inputs to ConvexPolygon
    are pretty high and we don't want to be responsible for reaching them.

run()

def lsst.pipe.tasks.selectImages.WcsSelectImagesTask.run	(		self,
			wcsList,
			bboxList,
			coordList,
			dataIds = None,
		**	kwargs
	)

Return indices of provided lists that meet the selection criteria

Parameters:
-----------
wcsList : `list` of `lsst.afw.geom.SkyWcs`
    specifying the WCS's of the input ccds to be selected
bboxList : `list` of `lsst.geom.Box2I`
    specifying the bounding boxes of the input ccds to be selected
coordList : `list` of `lsst.geom.SpherePoint`
    ICRS coordinates specifying boundary of the patch.

Returns:
--------
result: `list` of `int`
    of indices of selected ccds

runDataRef()

def lsst.pipe.tasks.selectImages.WcsSelectImagesTask.runDataRef	(		self,
			dataRef,
			coordList,
			makeDataRefList = True,
			selectDataList = []
	)

Select images in the selectDataList that overlap the patch

This method is the old entry point for the Gen2 commandline tasks and drivers
Will be deprecated in v22.

@param dataRef: Data reference for coadd/tempExp (with tract, patch)
@param coordList: List of ICRS coordinates (lsst.geom.SpherePoint) specifying boundary of patch
@param makeDataRefList: Construct a list of data references?
@param selectDataList: List of SelectStruct, to consider for selection
