D. B. Malesani (Radboud Univ. and DAWN/NBI) reports:
The GRB 211211A E_iso value reported by Malesani et al. (GCN 31221) is
incorrect. Using the Fermi GBM fluence 5.4*10^-4 erg cm^-2 (Mangan et
al., GCN 31210), the corresponding E_iso value is 6.9*10^51 erg,
assuming the GRB is at z = 0.076.
The conclusion that GRB 211211A would not be consistent with the Amati
relation if at z = 0.076 was based on the correct E_iso value, and still
holds. This may indicate that the GRB lies in fact at a higher redshift.
I sincerely apologize for any confusion caused by this mistake, and I am
grateful to those who pointed it out, including Peter Veres, D.
Alexander Kann, and Lorenzo Amati. No blame should be assigned to the
other co-authors of GCN 31221, who saw an earlier draft which did not
contain the mistake.
