Tests of the range of templates acceptance in momentum and theta shows that we can use the the grid 1 % ptot in momentum and 0.2 degrees in theta, but especially at higher momenta the grid can not be coarser.

Similar tests of the range of templates acceptance in theta and z position of the vertex prove that we can not use the same templates for vertexes more than 0.05 cm distant, if we want to reconstruct highest momentum particles.

Deviations due to the multiple scattering in the beam pipe and silicon planes can be calculated theoretically and compared with deviations from simulations.

With each templates additional information on the change of the deviations with changing parameters of the ideal track is stored. This enables to calculate more accurate estimate of total momentum and emission angle theta for each track candidate, and then calculate corrected chi2. Corrected chi2 gives much higher probability of the candidates with parameters different than those of the template, thus the acceptance range of templates is signifficantly increased.
