Get tracklet r-phi resolution for given phi angle Resolution depends on the track angle sin(phi) = snp and is approximated by the formula sigma_y(snp) = sqrt(a^2 + c^2 * (snp - b)^2) more details are given in http://cds.cern.ch/record/2724259 in section 5.3.3

Parameters

phi	angle of related track

Returns

sigma_y^2 of tracklet
