The present invention is a tolerance adjusting attachment which is part of a bracket member used for providing proper alignment between more than one externally visible component. The apparatus includes an analysis unit, a first generating unit, and a second generating unit. As another example, a stored trajectory of a desired witness structure temperature or other property can be used as a basis for control during a processing cycle. The first and second side members and the filter media may have a perimeter cross-section substantially perpendicular to the longitudinal direction, and the filter element may further include a locating flange extending substantially around the perimeter cross-section and transverse to the longitudinal direction, wherein the locating flange does not lie within a single plane.
