Consequences of the WFC3 IR detector 24 degrees tilt
... The current optical design for the IR channel of WFC3 has a focal plane tilted by 24 degrees to the chief ray due to the off-axis correcting optics. A similar design is used in, e.g., ACS but its effect is potentially amplified in WFC3 because of the bigger angle (it is only 11 degrees in ACS) and t ...
