12.7 ACS Aperture Coordinate System
Figure 12.1 shows how the POS-TARG coordinates, X and Y, are related to the U2,U3 and detector Axis1 and Axis2 directions. The Y axis is parallel to Axis2. The X axis is normal to Y but differs from the Axis1 direction by about 5 degrees. This diagram correctly shows the WFC and HRC orientations, but it does not represent their relative sizes or positions.
