Function lsst::meas::astrom::compose(geom::AffineTransform const&, PolynomialTransform const&)

Function Documentation

PolynomialTransform lsst::meas::astrom::compose(geom::AffineTransform const &t1, PolynomialTransform const &t2)

Return a PolynomialTransform that is equivalent to the composition t1(t2())

The returned composition would be exact in ideal arithmetic, but may suffer from significant round-off error for high-order polynomials.
