Extended Data Fig. 4: Upper limits on fast radio transients from other flares of SGR 1935+2154 observable by STARE2.
From: A fast radio burst associated with a Galactic magnetar
The ordinate shows the 7.3σ upper limit on the fluence of a potential burst in Jy ms1/2, and the abscissa shows the times (in MJD) of reported flares from SGR 1935+2154. The derivation of the upper limits is described in Methods. We note that our three-station system was observing only during the flares between MJD 58966 and MJD 58987, shown in black. For the other flares, only our stations at OVRO and GDSCC were observing, shown in red. We show FRB 200428 in blue; the error bar represents the standard error in the measured fluence.
