Error Definitions

This chapter describes the commands which provide error assignment and output of errors assigned to elements. It is possible to assign alignment errors and field errors to single beam elements or to ranges or classes of beam elements.

Elements, classes or ranges of elements are selected by the SELECT command.

ATTENTION: since errors can only be assigned to machine elements, it is necessary to FLATTEN a sequence if it includes other sequences.

Errors can be specified both with a constant or random values. Error definitions consist of four types of statements listed below. They may be entered after having selected a beam line by means of a USE command.

WARNING: any further USE command will destroy the assigned errors. Use the ESAVE option to save and reload errors.
