TAIGA-HiSCORE is an array of wide-angle air-Cherenkov detectors distributed on the area of 1 km$^2$. It is a part of a hybrid gamma-ray observatory TAIGA which combines imaging and timing methods to detect Cherenkov emission from extensive air showers. To collect Cherenkov light TAIGA-HiSCORE uses parabolic light guides - Winston cones, - combined with PMTs. We present the results of measurements of angular sensitivity of "PMT+cone" unit. This angular characteristic distorts a signal of initial event flux. To obtain an original signal we correct this distortion using weight functions. This corrections can be used for detection of gamma-ray sources.
