The expected offset and elongation of the Moon shadow due to the geomagnetic field are clearly observed. A determination of the angular resolution and pointing error has beem performed through this observation. A preliminary upper limit of the antiproton to proton ratio in cosmic rays is given in the TeV region.", "revisions": [ { "version": "v1", "updated": "2002-10-15T14:49:27.000Z" } ], "analyses": { "keywords": [ "cosmic rays", "proton ratio", "antiproton", "measurement", "moon shadow effect" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 599779, "adsabs": "2002astro.ph.10334P" } } }
