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 2017 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.
