Abstract
We use likelihood approach for search for local astrophysical neutrino sources in unbinned versus binned methods with Baikal deep underwater telescopes. We analyze neutrino data sample selected with NT200 telescope for 1038 live days by scanning a celestial map with different nets and for listed gamma ray sources. Significance of most probable location of enhance in measured number of events is found to be less than one sigma. We obtain the upper limits and a sensitivity at 90\% C.L. on neutrino fluxes from listed sources for NT200 and NT1000 correspondingly.
