Based on the method presented in Y.H. Wang et al. "Localization of Gamma-Ray Bursts Using the polarimeter POLAR" 2020 (submitted to NIM A) the GRB had an off-axis angle > 90 degrees. Due to the large uncertainties for a response with an off-axis angle >90 degrees (due to materials in the vicinity of POLAR) no proper response could be produced for this GRB. A photon list can be requested.
