After fits have been performed, after_fit() and report_fit()Īre called. If this method is not overridden, fits will be performed automatically on the mean values calculatedĬalls before_analyze(), checks to see if fits should be performed, and performs a fit usingĮach model that has been registered as performing a fit (i.e. Interface method (optional, has default behavior) Mean – the mean number of counts collected at the scan point over all measurements. Point – the scan point (float for 1D scans, a list of two integers for 2D scans) I_point – point index (integer for 1D scans, a list of two inetegers for 2D scans) this callback will not be called if scan is terminated _after_scan_point ( i_point, point, mean ) ¶ Scan extension callback executed during the scan loop after a scan point has completed.Įxecutes after all data has been collected, datasets have been mutated, calculations have been performed, this callback will not be called before yielding to higher priority experiment Internal callback called after the scan and any higher priority experiments have completed. _load_x_offset ( ) ¶ _module_ = 'scan_' ¶ _after_scan ( ) ¶ See help(type(self)) for accurate signature. (see the ‘Scan Callbacks’ section for additional information) _get_x_offset ( ) ¶ _init_ ( managers_or_parent, * args, ** kwargs ) ¶ The following callback methods are available, Using callbacks allowsĬode in child classes to execute at predefined stages of the scan. Various callbacks are provided that execute at certain moments of a scan’s life cycle. Provides dataset initialization, mutating, fitting, validation of data, pausing/resuming, and Provides a generalized framework for executing a scan.
