Rj(c) is the set of all cooperating schools within Sj(c),
SCH_BWTjs is the school base weight for school s in jurisdiction j,
SCH_TRIMjs is the school-level weight trimming factor for school s in jurisdiction j,
SCHSESWTjs is the school-level session assignment weight for school s in jurisdiction j, and
