Abstract: After a brief review of the electroweak radiative corrections to gauge-bosonself-energies, otherwise known as the direct and oblique corrections, a toolfor calculation of the oblique parameters is presented. This tool, namedOPUCEM, brings together formulas from multiple physics models and provides anerror-checking machinery to improve reliability of numerical results. It alsosets a novel example for an -open-formula- concept, which is an attempt toimprove the reliability and reproducibility of computations in scientificpublications by encouraging the authors to open-source their numericalcalculation programs. Finally, we demonstrate the use of OPUCEM in two detailedcase studies related to the fourth Standard Model family. The first is ageneric fourth family study to find relations between the parameters compatiblewith the EW precision data and the second is the particular study of the FlavorDemocracy predictions for both Dirac and Majorana-type neutrinos.
