WarpedPsf(boost::shared_ptr< afw::detection::Psf const > undistortedPsf, boost::shared_ptr< afw::geom::TransformPoint2ToPoint2 const > distortion, boost::shared_ptr< afw::math::WarpingControl const > control)
Construct WarpedPsf from unwarped psf and distortion.
Definition: WarpedPsf.cc:139
virtual afw::geom::Point2D getAveragePosition() const
Return the average of the positions of the stars that went into this Psf.

Definition: WarpedPsf.cc:203
virtual boost::shared_ptr< afw::detection::Psf > resized(int width, int height) const
Return a clone with specified kernel dimensions.
Definition: WarpedPsf.cc:196
virtual boost::shared_ptr< afw::detection::Psf > clone() const
Polymorphic deep copy. Usually unnecessary, as Psfs are immutable.
Definition: WarpedPsf.cc:192
An intermediate base class for Psfs that use an image representation.
