NIKA Run#3 Summary of Off line processing Results
Focal Plane Geometry and Beams
Both RZ (Mopsic) and NP (IDL, from This pdf) have found a distortion of the focal plane geometry well beyond the expected one.
The focal plane distortion affects the beams in a correlated fashion with the Focal Plane Geometry distortion. This points towards a general optical distortion common to both detectors (an optical element is misplaced in the optical train).
