  "body": "N. Dagoneau, A. Saccardi (CEA), report on behalf of the SVOM/ECLAIRs team:\n\nUsing the event-by-event data downloaded through the X-band ground station, we report further analysis of ECLAIRs observations of GRB 260705A (SVOM burst-id sb26070502). \n\nThe burst that triggered ECLAIRs onboard (GCN 45079) consists of a single broad peak lightcurve with a duration of T90 = 35.55 -9.04 / +6.05 (4-80 keV). \n\nThe time-averaged spectrum (from T0-5.49 s to T0+29.72 s) in the energy range 5-120 keV is best fit by a powerlaw with an index of -1.68 ± 0.09. With this model, the 4-120 keV fluence is (1.053 ± 0.087)*E-6 erg/cm² and the 4-120 keV photon flux is 1.002 ± 0.059 ph/cm²/s.\n\nAll the quoted errors are at the 68% confidence level.\n\nThe Space-based multi-band astronomical Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA), French Space Agency (CNES), and the Chinese Academy of Sciences (CAS), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe.\n\nThe SVOM/ECLAIRs point of contact for this burst is: N.
