Note for beginner
- Time
- JST or GPS time
- IFO config = Interferometer configuration
- Yarm cavity : Lock the Yarm cavity by feedback to the IMC length (Almost frequency noise evaluated by Yarm length)
- FPMI : Fabry-Perot Michelson interferometer. The h-of-t signal is calculated from DARM displacement
- Main channel
- We should analyze this channel as h(t) channel
- (1) K1:CAL-CS_PROC_XARM_FREQUENCY_DQ
- Unit is Hz, because of calculating the IR laser frequency noise
- Even though Yarm lock, the channel name is XARM. The same strategy to keep the cavity.
- (2) K1:CAL-CS_PROC_DARM_DISPLACEMENT_DQn
DARM displacement [nm or m] there are still some bugs in the online model, I will summarize later Fixed(Due to the fail of the filter)
- (3) K1:CAL-CS_PROC_MICH_DISPLACEMENT_DQ
- Ogaki-san and cal team sometimes update the optical efficiency and actuator efficiency
- (4) K1:CAL-CS_PROC_SRCL_DISPLACEMENT_DQ
- First opt gain and act eff measurement 2019/08/30
- klog
- Information related to the run is summarized here
- state flag = guardian state flag
- When this state flag and K1:MIF-WE_ARE_DOING_NOTHING = 0 are satisfied, we should analyze data.
- Memo
- In the future, we want to do the calibration line injection, PEM injection, add the excitation and check the noise, hardware injection, and so on.
- We will write following information.
