Satellite Meeting on Calibration and related grants projects

Date : April/22

Time : 9:00 - 15:30

Place : the same room with F2F.

Presentation registration of the satellite meeting should be made directly to Calibration subgroup and leader of related grants ; kanda\_at\_sci.osaka-cu.ac.jp, tomaru\_at\_post.kek.jp, iyuki\_at\_post.kek.jp

Discussion Program and Agenda

I. Calibration and hardware related issues

We would like to have general discussion on the KAGAR calibration, $h(t)$ reconstruction and hardware related issues.

9:00-12:00 Remark and Sharing the Current Status of calibration around O3

chair: T.Tomaru

Current Status (Y.Inoue)
- end-to-end of KAGRA calibration
- Flow chart of works and dedicated persons
  - Who is working on What/How ?
Remark the goal/target of O3
- goal / target !?
- Q: Are we ready for O3 ?
  - prepared/finished items: , , , ,
  - remain items : , , , ,
  - options : , , ,

GW (Gravitational Wave) Metrology Workshop report (Y.Inoue)slide
LVK cross check

Crosscheck meeting with LVK (Homework) will be held on July (We have this meeting every seasons). At that time, we discuss the following things:

-Pcal error budget -> https://dcc.ligo.org/LIGO-T1800046 (-Error budget of h(t) (Engineering run))
Toward O4
- Preparation for O4
- How /What goal for the finish of O4 in KAGRA ?

13:00-14:00 Technical issues on h(t) reconstruction

chair : N.Kanda

Hardware conditions/evaluations (con't for discussion in a.m.)
Proc. Data (T.Yamamoto and/or T.Sawada)
- C1#
  - Filter design
  - Expected quality
  - Latency
  - variation of files, i.e. length, recorded channels, etc.
  - decisions for O3
- C2#
  - Target quality
  - Cadence of offline generation
  - Necessary items for C2#
Data files (N.Kanda)
- Data flow overview
- Variations including low latency files

II. Data Analysis related with Calibration

chair : Y.Inoue

14:15-15:30

GW waveform injection (T.Sawada)
Simulation (S.Tsuchida)
Analysis topics related with calibration

III. Grants strategy (closed session)
