TL;DR: In this paper, the optical and IR afterglow measurements reported here may provide the first observational evidence of beaming in a GRB, thereby reducing the required energy consumption to a level where stellar death models are still tenable.

TL;DR: In this paper , the authors provide empirical values of loggf based on abundances of classical Cepheids obtained with optical spectra in Luck (2018), in order to establish the consistency between optical and infrared abundance results.
