00925njm 22002777a 4500 dc Vázquez Peñas, José Ramón author Rosado Vélez, Jaime author García Pinto, Diego author Arqueros Martínez, Fernando author 2013 The fluorescence yield data used for shower reconstruction in the Auger, HiRes and TA experiments are different, not only in the overall absolute value but also in the wavelength spectrum and the various atmospheric dependencies. The effect on the energy reconstruction of using different fluorescence yield parameterizations is discussed. In addition, the impact of a change in the fluorescence spectrum depends on the optical efficiency of the telescopes. A simple analytical procedure allows us to evaluate the combined effect of fluorescence yield and optical efficiency showing a non-negligible deviation between the energy scales of TA and Auger. However no relevant effect is found in the comparison between HiRes and Auger. Finally we show that a similar procedure could also be applied with real data. 978-2-7598-1025-3 10.1051/epjconf/20135310002 https://hdl.handle.net/20.500.14352/45599 http://dx.doi.org/10.1051/epjconf/20135310002 http://www.epj-conferences.org/ The effect of the fluorescence yield selection on the energy scales of Auger, HiRes and TA
