Data Analysis
Data creation:[edit | edit source]
Data are created by Alberto's software -> GUFI with the following format:
- A folder labelled "day_time"
- Inside there are two kind of file: a logbook and a file for each enabled ROC
-Format of the logbook ??
-Format of the data ??
Data analysis:[edit | edit source]
The data are threated in two step:
1- Wenlong code, renamed "TIGER Event Reconstruction" that convert the data collected by each ROC to a root file
2- GRAAL to digitize and clusterize the hit from each channel/strip and then performe the tracking
TIGER Event Reconstruction[edit | edit source]
The creation of the root file follow several steps:
1- [Script in python] Deconding the data from the ROC and it extract the variables into a root file: ecoarse, efine, tcoarse, tfine, strip ID, chip ID, FEB ID, ROC ID, frameword, altro?
2- Unify the root files from each ROC
3- [ana.C] Calibrate charge and time as a function of the FEB/channel
4- [event.C] Sort the entries as a function of the time, measure the trigger time and create the event
GRAAL[edit | edit source]
The reconstruction and the analysis in GRAAL is divided in three steps:
1- [$graal/src/rec] Prenalysis on the hits and clusterization
2- [$graal/src/evt] Tracking and good cluster selection
3- [$graal/src/ana] Generation of the PDF with the informations of charge, time and occupancy as a function of the FEB
