Notes. The GRB host and HII regions were measured from integrated spectra extracted from the MUSE cube, values at the GRB site were obtained from the late time X-shooter spectrum, the spectrum of the companion was obtained from separate PMAS/CAHA observations of the galaxy. The values in “GRB site” refer to the values from the X-shooter spectrum. In the MUSE data, the [O II]λ3727,29 is out of range. Fluxes in units of 10−16 erg s−1 cm−2 and are corrected for Galactic and intrinsic extinction using the Balmer decrement.
