2. Content A very short review
The propose: Prepare SVOM BA with GWAC Events
The schedule (preliminary)
Current status and the schedule of GWAC
The schedule of SVOM/GWAC BA system

3. The strategy for SVOM to observe GW bursts
2015
2019
2022
Error box: ~600 Sq.Deg
~10 Sq.Deg.
GRM
Eclairs
MXT VT
GWAC
SRR, June 2015, Beijing

4. Chinese and French Joint Teams
SVOM triggers
GW triggers
GWAC
FSC
GFTs
CSC
Telescopes
Proposed this idea at JSC, 26 Sept., and discussed about it in IAP, 27 Sept. 2016

5. Main works for BA Scientific judgement of a burst
GRB validation mainly based on the VHF data
Supervise the notice/circular/report
To make the first circular for a given burst, which includes the information of all the instruments.
To coordinate the follow-ups
Notice: BA needs the supports from IS/IE/BAa
From Liping’s talk for this workshop

6. BA for SVOM GRBs vs BA for GWAC OTs
Scientific judgement of a burst
GRB validation mainly based on the VHF data
Supervise the notice/circular/report
To make the first circular for a given burst, which includes the information of all the instruments.
To coordinate the follow-ups
Notice: BA needs the supports from IS/IE/BAa
Eclairs--->GRBs
GWAC--->OTs
GWAC OTs need the same tasks as Eclairs GRBs.

7. The Propose to SVOM ground segment teams
To prepare SVOM BA with GWAC events
Design and build BA system;
Test and refine the system;
Train the BA team;
Before the launch of SVOM, SVOM have a very mature BA system!

8. Status: Mini-GWAC Mini-GWAC at Xinglong Obs.: 12 CANON EF 85/f1.2
12 U9000X CCD cameras
FoV: ~5000 Sq.Deg
Having capability to trigger OT:
Oct. 2015: in operation，
~10 flare stars detected, … 日

10. Status: GWAC 2014: GWAC working Model, 4 telescopes + one mount
2016: 8(Oct.)+10(Dec.) GWACs will be set up at Xinglong Obs.

11. Testing 8 GWACs, Fuzhou, July 28
10 GWACs more, Fuzhou, Sept. 23
4 GWAC on one mount, Nanjing, Sept 13

12. Status: GFTs for GWAC 2台60厘米望远镜：广西大学提供，2013年8月到货安装；
1台30厘米望远镜：淮北师范大学提供，2015年11月安装完毕
