By offsetting the quadrupole doublets after the dipoles, access to the photon beam lines was made more convenient, but destroys the symmetry of the element placement. The common bussing of the quadrupole doublets and the triplets make the Twiss functions asymmetric through the long straight section and a large negative dispersion in this region. The large value of dispersion around the period, although not by itself bad, limits the natural emittance of this lattice and makes resonance corrections difficult without influencing the chromatic properties of this lattice
