class	lsst::jointcal::AstrometryTransformPolynomial
	Polynomial transformation class. More...
class	lsst::jointcal::AstrometryTransformLinear
	implements the linear transformations (6 real coefficients). More...
class	lsst::jointcal::AstrometryTransformLinearShift
	just here to provide a specialized constructor, and fit. More...
class	lsst::jointcal::AstrometryTransformLinearRot
	just here to provide a specialized constructor, and fit. More...
class	lsst::jointcal::AstrometryTransformLinearScale

class	lsst::jointcal::TanSipPixelToRaDec
	Implements the (forward) SIP distorsion scheme. More...
class	lsst::jointcal::TanRaDecToPixel
	This one is the Tangent Plane (called gnomonic) projection (from celestial sphere to tangent plane). More...
class	lsst::jointcal::UserTransform
