Blown films and processes of forming the same are described herein. Thus, -2R*1S*,5S*+2R*1S*,5R*-\u03b1,\u03b1\u2032-phenylmethyliminobisbis6-fluoro-3,4-dihydro-2H-1-benzopyran-2-methanol is dissolved in diisopropyl ether at reflux temperature and cooled to below about 30\xb0 C. If the first module has passed verification, a pre-verification constraint on a constrained module is read, if any. The difference between the outputs of the integrators is then sampled at the triggering signal frequency.
