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