|
PRM/SRM OSEM input calibration
- I realized I had not yet updated
the input OSEM cts2um calibration. For PRM and SRM, I changed each cts2um filter gain from 0.36 ---> 0.0417 (factor
of 8.64). |

To further homogenize the suspensions, we did the following changes.
- Turned on DECIMATION in PR2 URCOIL
- Changed +/- 13 in SDCOIL_GAIN of SR2,LO1,LO2,AS1,AS4 to +/-1 and increased SUSSIDE_GAIN accordingly |

While aligning today I realized the cavAlign step sizes and step factors had not been updated after the upgrade.
Here are the new MEDM command arguments to launch cavAlign. Only factors not equal to 1
are listed. The updates made by me are in red |
