Abstract
Results on TeV gamma-ray point source search using data taken from the Tibet HD (Feb. 1997 -- Sep. 1999) and Tibet III (Nov. 1999 -- Oct. 2001) arrays are presented. From 0 degree to 60 degree in declination (Dec), significan t excesses from the well-known steady source Crab Nebula and the high state of the flare type source Markarian 421 ar e observed. Because the levels of significance from other positions are not sufficiently high, a 90% confidence leve l (CL) upper limit on the flux is set assuming a Crab like energy spectrum. To allow cross-checking, two independentl y developed analyses are used in this work.
