Description of Some Ultra High Energy Cosmic Ray Observed with the Pierre Auger Observatory
January 2005; 8 pp.; In English Report No.(s): DE2005-15020254; FERMILAB-CONF-05-276; No Copyright; Avail.: Department of Energy Information Bridge
A discussion is given of the highest energy events so far recorded by the Pierre Auger Observatory. We present these to illustrate the quality of the information that they contain. The surface detectors are used to measure a rich set of parameters that will eventually help characterise the mass of the incoming primary particle. NTIS

Detection of Very Inclined Showers with Auger Observatory
January 2005; 8 pp.; In English Report No.(s): DE2005-15020253; FERMILBA-CONF-05-277; No Copyright; Avail.: National Technical Information Service (NTIS)
The Pierre Auger Observatory can detect air showers with high efficiency at large zenith angles with both the fluorescence and surface detectors. Since half the available solid angle corresponds to zeniths between 60 and 90 degrees, a large number of inclined events can be expected and are indeed observed. In this paper, we characterise the inclined air showers detected by the Observatory and we present the aperture for inclined showers and an outlook of the results that can be obtained in future studies of the inclined data set.
