Calibrations
I expect to break each detector/calibration out into its own wiki page as they mature, but for now I think it is best to work on this single (big) page until we have settled on a "good" template.
Basic Template for each Detector/Calibration Procedure
For each detector subsystem we would like to capture/document the following information:
- A list of all (or at least the most useful) ROOT tree variables associated with this detector
- Description of the calibration algorithm (That is, how is it supposed to work -- what is the logic behind it?)
- Files involved in the calibration
- THc* or THa* modules that are needed/used
- Database files that will be modified
- Scripts that will be used
- Dependencies of this calibration
- Reference time cuts should be verified
- FADC 'hit selection' timing cuts should be verified
- Calorimeter calibration relies on good optics calibration for momentum determination
- If tight timing cuts are used, then the hodoscopes may need to be calibrated first, etc
- ... etc
- Provide a step-by-step "Howto" that shows
- What commands/scripts need to be run, in what order.
- How do you verify that various cuts (ref times, trigger types, etc) are correct before you run the script(s)?
- What do you look for to verify that the code has run correctly after you run the script(s)?
- Common Pitfalls / Things to watch for
- I have found it useful in the past to provide a list of common symptoms and solutions that people may run into.
