本文介绍了利用西藏HD（1997年2月~ 1999年9月）和西藏III（1999年11月~ 2001年10月）阵列的数据进行TeV γ点源稳态搜索的结果。在10月0° ~ 60°范围内，观测到来自著名的稳定源蟹状星云和耀斑型源Markarian 421的高态的显著过量。由于其他位置的显著性水平不够高，假设不同的幂律谱，设定通量的90%置信水平上限。为了进行交叉检查，在这项工作中使用了两个独立开发的分析。
Results of a steady TeV γ-ray point-source search using data taken from the Tibet HD (1997 February-1999 September) and Tibet III (1999 November-2001 October) arrays are presented. From 0° to 60° in declination, significant excesses from the well-known steady source Crab Nebula and the high state of the flare-type source Markarian 421 are observed. Because the levels of significance from other positions are not sufficiently high, 90% confidence level upper limits on the flux are set assuming different power-law spectra. To allow cross-checking, two independently developed analyses are used in this work.
