Latest revision as of 02:18, 14 November 2014
Below is the latest version of 'db_run.dat' in the analyzer database. It should be ready to use now. I will update here if I think of anything to change. Please let me know if there is any issue.
-Min
How To Use
Put this file in $DB_DIR. Analyzer will use it.
Details
First, time is the prestart event time obtained from raw data file.
- Thanks to Chao for providing the time
The ebeam, L/R.pcentral are average values of the respective epics variables during each run obtained from raw data files.
The target type is determined from target encoder values. The ranges can be found at the very end of this page.
- The target encoder variable didn't start reporting accurately until run 3220/22305 [1]. Fortunately, there is no g2p production run before this point, thus all masses (MA) are assigned as carbon mass.
- Thanks to Chao and Ryan for providing the EPICS and target information
The L/R.theta is assigned as 5.69 temporarily. These variables will be updated after pointing calibration is done.
