changes to the IMC IN beam after PSL work today
Changes are seen on both GigE cameras. Using the path length to the camera, and the pixel size, I calculated the angle change of the beam on IO GigE 2, and used that to calculate the change at 20m, the distance to MC2, and of course these are approximations, based on the current installation.
| change in pixels | change in mm @ MC2 | |
| IO GigE 2 X (IMC_IN) | 4.5 | 1.0 |
| IO GigE 2 Y (IMC_IN) | 9 | 2.0 |
