_trimToPatch()

lsst.pipe.tasks.drpAssociationPipe._trimToPatch ( self, cat, innerPatchBox, innerTractSkyRegion, wcs )

protected

Create generator testing if a set of DiaSources are in the
patch/tract.

Parameters
----------
cat : `pandas.DataFrame`
    Catalog of DiaSources to test within patch/tract.
innerPatchBox : `lsst.geom.Box2D`
    Bounding box of the patch.
wcs : `lsst.geom.SkyWcs`
    Wcs of the tract.

Returns
------
isInPatch : `numpy.ndarray`, (N,)
    Booleans representing if the DiaSources are contained within the
    current patch and tract.
