Better diagonalization of PRM input matrix |
|
|
The values here should replace those in entry #851 from yesterday.
After checking the results of the input matrix diagonalization, I have determined that Sonia's method (described in LIGO-T070168) is more effective at isolating the eigenmodes than Shihori's method (LIGO-T040054).
So, the actual new PRM input matrices are as follows:
|
| POS | PIT | YAW
| |
UL | 0.9678 | 1.000 | 0.7321
| |
UR | 1.000 | 0.8025 | -0.9993
| |
LR | 0.7235 | -1.1230 | -1.0129
| |
LL | 0.6648 | -1.0452 | 1.0000
|
Attached are plots of the spectra of the eigenmodes, using both Shihori's and Sonia's methods. Note that there isn't a good way to get the side peak out of the eigenmodes.
I've put these into the SUS-PRM MEDM screen. |
