We perform two Rayleigh analyses, one in the right ascension and one in the azimuth angle distributions, that are sensitive to modulations in right ascension and declination, respectively. The largest departure from isotropy appears in the E\gt 8 EeV energy bin, with an amplitude for the first harmonic in right ascension r1α =(4.4+/- 1.0)× {{10}-2}, that has a chance probability P(≥slant r1α )=6.4× {{10}-5}, reinforcing the hint previously reported with vertical events alone....STAMPAenLarge Scale Distribution of Ultra High Energy Cosmic Rays Detected at the Pierre Auger Observatory with Zenith Angles up to 80°Article10.1088/0004-637X/802/2/1112-s2.0-84926512793000353014500039https://iopscience.iop.org/article/10.1088/0004-637X/802/2/1112015ApJ...802..111AFIS/01 - FISICA SPERIMENTALE
