I modified the real-time model in order to accomodate bandpass fillters and new DAQ channels. See 11788.
- For the most part I used the same scheme as Type A.
- As agreed in the previous meeting I added a matrix ramp switch in order to transit from velocity damping to bandpass filters.
- The medm screen was modified accordingly.
- I realized yesterday I hadn't added a monitor for the output of the new filters banks in the EUL basis. It's been added to the real-time model, it compiles but still has to be installed.
- Real-time models for SR suspensionsmust be compiled and installed.
Together with Terrence I modified vistools in order to generate functions to manipulate added filter banks. See 11788.
- The future of vistools looks quite gray (the code is complicated and not commented) but I still took some notes.
- I began adding code for the OBSERVATION state in a draft file.
- There was an agreement with Okutomi-san to change Type B medm screens for something more illustrative of the signal paths.
- The temperature in the BS area has increased. It's been lately between 23.7 and 23.8 degrees. The actuation on the top filter used to be -23,000 counts and is now -13,500 counts.
Yamada-kun and Yokozawa-san measured transfer functions from BS to DARM and calculated the noise contribution. See 11676, 11724, 11707.
- The results are affected by an error in the calibration and are yet to be corrected.
The contributions of TM_DAMP_L and TM_DAMP_Y were considered to be high. These filters are supposed to be off in OBSERVATION state. See this plot.
These filters were rolled-off and the a new estimation was calculated. See this other plot.
- The roll-off of TM_DAMP_Y was conservative.
- For the purposes of ASC the diagonalization of the TM actuation with respect to the oplev was removed by commissioners and replaced by their own coil balancing and drivealign diagonalization. I couldn't find a klog for this.
