- fabrication and installation errors (sensor profile/height and raft mounting z-position repeatability, albeit current estimates for the later one seem to be small)
- Cumulative sensor height distributions at 31 field positions across the focal plane (provided by AndyR, 9/3/14)
- For example, file cumdist_rad0.379_az120.qdp is for field point (radius=0.379 degree, azimuth angle=120 degree).
3 levels of alignment: Sensor, Sensor-on-Raft, and Raft-on-Grid.
- This plot shows the cumulative distributions for each of 31 sample locations, color coded by radial distance.
- Cumulative distributions provided in two-column format.
