- getAverageColor(self: lsst.afw.detection.Psf) lsst.afw.image._imageLib.Color ¶
- getAveragePosition() Point2D ¶
Get a position where PSF can be evaluated on a patch.
This defaults to the center of the patch bounding box, unless there are no inputs there. In that case, it switches to find an arbitrary cell, typically at a corner that has inputs and returns the center position of the cell.
