A program for inspection of bubble chamber photographs is described. The program was developed for a DEC-10 computer and is designed for PUOS-2M and PUOS-4 semiautomatic inspection and measuring projectors. Formalization of the inspection procedure allows it to be used for various physics experiments. As an example the authors consider the problem of the physical inspection in an experiment on scattering of kaons plus with momenta of 70 GeV/c by protons performed in a BEBC chamber. Primary vertices were analyzed in the following cases: low quality of reconstruction of parameters in the geometric program; lack of agreement of the number of reconstructed tracks with that indicated by inspection; and unmeasured events and events with candidate tracks for identification of proton tracks by degree of ionization. The performance of the program in these cases is evaluated. The program has been used to process 50,000 events recorded with a BEBC chamber as well as experiments recorded with the SCAT chamber and the European Hybrid Spectrometer using the RCBC, LEBC and HOLEBC chambers.
