        Parameters

        ----------

        detector : `int`

            Detector ID to get image data for.

        imageFactory : `lsst.afw.image.Image`

            Type of image to construct.

        binSize : `int`

            Binsize to use to recompute dimensions.

        -------

        image : `lsst.afw.image.Image`

            Appropriately rotated, binned, and transformed

            image to be mosaicked.

        detector : `lsst.afw.cameraGeom.Detector`

            Camera detector that the returned image data
