  The result of studies of the energy and spatial resolution of a large volume
liquid scintillator detector are presented. The relations are obtained, which
allows an estimation of the detector's energy and spatial resolutions without
modeling. The relations are verified with the data obtained with the CTF
detector, which is the prototype of the new detector for solar neutrinos,
called Borexino. An event reconstruction technique using charge and time data
from the PMTs is analyzed using the obtained relations in order to improve the
detector resolution. Algorithms for the energy and coordinates reconstruction
of events are presented
