Monitoring Configuration File Changes

The configuration files (e.g. FCAL_BCAL_PS_m9.conf) are stored in RCDB for each run, and contain all the relevant configuration variables. This link: Configuration File Changes: Spring 2018 provides a list of when the standard production configuration file changed (according to RCDB), and the difference with the previous configuration file. The specific run numbers for various trigger changes in the table above are derived from these configuration files.

Summary of Configuration Changes

Parameter Changed	Run Start	Comment
CDC time window delay	41482	Move hits closer to the beginning of the time window to reduce "shadowing" of signal hits
