A set of highly efficient coordinate transformations has been derived to convert between Cartesian coordinates in two different projection planes. The gain in execution speed is as great as a factor of 20 compared to the two‐step process of going from Cartesian coordinates in one plane to the celestial coordinates, and then to Cartesian coordinates in the second plane. The new coordinate transformations are successfully used by the Spitzer Space Telescope mosaicker MOPEX.
