The table below gives the OMC finesse calculations for the different modes of the carrier field. These were caclulated with the code [/ligo/gitcommon/labutils/omc_scan/fit_peak_w_args.py]. When the code is run, it prints the finesse out to the terminal. The GPS time used for these caclulations was 1393542033 and the duration was 80sec.
| Field | Mode | Fit Finesse | Data Finesse |
| Carrier | 00 | 404 | 389 |
| 10 | 395 | 401 | |
| 20 | 367 | 377 | |
| 30 | 336 | 296 | |
| 40 | 306 | 343 | |
| 50 | 268 | 10.9 |
This code could be improved becasuse the data finesse has the chance of miss identifying where the HWHM frequency is if there is a nearby peak. This was the case in carrier 50. We also need to add in the capability of including the q number as an argument to fit_peak_w_args.py so that we can compare the finesse for the same modes but seperated by an FSR.
The lower finesse as the mode increases is most likely due to the worse fit (the SNR is worse as the mode increases).
