About this version of CSPad alignment
- Sensors in quads are aligned individually (see CSPad Alignment of quads for cxi80410-r0628) using their natural coordinates as from the optical measurement (top-left corner is an origin, nearest point to the beam spot).
- Quads are rotated and inserted in uniform 2-D array with appropriate offsets.

CSPad Alignment of quads for cxi80410-r0628
Alignment tool
- Takes image of CSPad or quad from 2-D array
- Draw lines along the wire shadows
- Interactively adjust lines along the wire shadows
- Plots:
- image
- image profile
- deviation of the shadow "center of gravity" from line along the line
