Prepare SVOM BA with GWAC Events Wei Jianyan@SVOM joint team, NAOC Paris, Oct. 20, 2016

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

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

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

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

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.

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!

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, … 2013.05.28日 2015.12.18：a Flare star，Time scale~700秒 Light curve

A light curve of a flare star Light curves of GRBs （Wang et al. 2013） A light curve of a flare star （Mini-GWAC 2015） --------------------------------------------------------- T0 T-T0=30 sec -------------------------- Mini-GWAC ------------------------------- GWAC ----------------------------------------- 700sec

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

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