Descripción
In order to accurately reconstruct track and cascade events in a neutrino telescope, it is necessary to have information about the optical properties of the medium. The main purpose of the laser event analysis is to evaluate the light absorption length and the light scattering length in the deep Baikal water. Currently, the Baikal-GVD detector is equipped with 5 lasers with a wavelength of 532 nm, located on vertical strings at various depths. The lasers emit powerful flashes of light which are recorded by the Baikal-GVD optical modules. The positions of the lasers are reconstructed from the optical module data using a chi^2 fit, taking into account the anisotropic light emission pattern of the lasers. The optical parameters of the medium are estimated using the likelihood minimization method assisted with Monte-Carlo simulations.
