Host galaxy properties

Quantity Measured value Unit
Stellar mass (1.7 ± 0.1) × 1010 M
Star-formation rate 2.43 ± 0.13 M/yr
Metallicity 9.03+0.15-0.24 12+log(O/H)
E(B-V) 0.33 mag
Mass-weighted age 4.97+0.36-0.52 Gyr
FRB offset from galaxy center 1.3 ± 0.1 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
5.69+1.49-0.99
1.23+0.30-0.23
[OIII] λ 5007 0.38+0.21-0.11
[NII] λ 6584 2.53+0.60-0.47
Measurements are reported in units of 10-15 erg s-1 cm-2 and are corrected for Galactic dust using the E(B−V) values derived from Schlafly & Finkbeiner, 2011, ApJ, 737, 103.
