Skymap Differences. Assume both Dinnat and Floury skymaps are in J2000 system. Assume Floury map is in B1950 and Dinnat map is in J2000. Dinnat Map Transformed into the B1950 system. Floury Map assuming it was provided in B1950 system. Difference map reveals unexpected differences. - PowerPoint PPT Presentation
