class
TanRaDecToPixel
: public lsst::jointcal::AstrometryTransform¶ This one is the Tangent Plane (called gnomonic) projection (from celestial sphere to tangent plane)
this transform does not implement corrections, since they are defined the other way around (from pixels to sky), and not invertible analytically. The inversion of tangent point WCS (TanPixelToRaDec) is obtained via inverseTransform().
