Sky distribution in equatorial coordinates of the GROND GRB sample. We note the lack of extinction bias towards the Galactic plane, made evident based on the ratio of detected and non-detected afterglows. The apparent ‘concentration’ of observed GRBs towards the South Pole is due to a 2σ lack of triggers in the −40° < Dec < −50° range: 32 versus a mean of 50 (between −70° and +20°). These results are updated from Greiner (2019).
