A functional coating (11) between the substrate (3) and the reflective coating (5) has a local form variation (19) for correcting the surface form of the mirror (1), wherein the local form variation (19) is brought about by a local variation in the chemical composition of the functional coating (11) and wherein a thickness of the reflective coating (5) is not changed by the local variation in the chemical composition of the functional coating (11). The local variation in the chemical composition of the functional coating (11) can be brought about by bombardment with particles (15), for example with hydrogen ions.

Abstract: Methods and apparatuses enable generation of an executed workload electronic record. The executed workload record indicates data related to one or more performance metrics by which performance of a work task is evaluated. One such performance metric is an expected time for completion of the task. Performance of the task can be monitored to determine an actual completion time for the task to compare against an expected completion time. The executed workload record can be used for evaluation of workers. Executed workload records provide centralized, aggregatable information for evaluation purposes.
