Host galaxy properties

Quantity Measured value Unit
Stellar mass ∼ 0.75 × 109 M
Star-formation rate 0.27 ± 0.08 M/yr
Metallicity 8.71+0.17-0.28 12+log(O/H)
Half-light radius 2.15 ± 0.11 kpc
FRB offset from galaxy center 11.4 ± 3.5 kpc
Gas-phase metallicities are derived using the O3N2 calibration from Hirschauer et al., 2018, AJ, 155, 82.

Emission line fluxes

Emission line Measured value
0.49 ± 0.05
