= 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''

 1. Current Status  (Y.Inoue)[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10135|slide]]
	* end-to-end of KAGRA calibration
	* Flow chart of works and dedicated persons
		* Who is working on What/How ?

 1. Remark the goal/target of O3

 1.#3 GW (Gravitational Wave) Metrology Workshop report (Y.Inoue)[[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=10123|slide]]
 1. 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)) 
 1. Toward O4[[https://gwdoc.icrr.u-tokyo.ac.jp/DocDB/0101/G1910136/001/Toward_04.pdf|slide]]
	* Preparation for O4
	* How /What goal for the finish of O4 in KAGRA ?
