Resumen:
In this note we present an update of the large scale anisotropy study using the East-West method, applied to the events detected with the inll array. The scanned energy range was 10**16 eV < E < 10**19 eV, using data collected until March 31st 2012. We use three di ferent reconstructions to compare the results. Herald inll reconstruction and Offline from both Karlsruhe and ITeDA. No signicant signal of a dipolar modulation in right ascension was found and thus a 99% CL upper limit for the dipole component in the equatorial direction is derived. An approximately constant value of the phase of the rst harmonic in right ascension for energies below 10**18 eV is apparent, with values of Phi = (260 +/- 31) deg, ITeDA = (240 +/- 34) deg, KG = (275 +/- 39) deg. These three values are consistent between each other and compatible with a maximum towards the right ascension of the Galactic Center. The results are also consistent with those obtained with the mainarray in the overlapping energy range.
