TBTelescope-TrackingInfo

Home-made module for Corryvreckan - Telescope raw data analysis software

Thanks to the helps from Drs Adrian Herkert, Oleksandr Borysov, and Roma Bugiel.

USAGE

1. Clone the folder to [corryvrackan]/src/modules/
2. Go to [corryvrackan]/build or other customised build folder, and re-make the software by:

cmake
make
make install

3. Add the following lines in the .conf file:

[TrackingInfo]
z_ref = 1000    # by default the reference plane is set at 1000 mm
z_dut = 1500    # change the number to the DUT's z coordinate in mm

OUTPUT

Like the other module's, the information extracted by this module should appear in the output root file of Corryvreckan under the TDirectory TrackingInfo, where a TTree Tracks can be found. The TTree contains the following entries:

• vector x/y_ref: the transverse coordinates of the track(s) hitting on the reference plane
• vector x/y_dut: the transverse coordinates of the track(s) hitting on the detector's plane
• vector triggerid: the universal/extended trigger-logic-unit (TLU) ID for each event
• vector timestamp: the time of each event Notes:

1. The number of track(s) in each event, namely a period of time determined by the telescope, could be 0, 1 (the most probable case), or even more.
2. The raw TLU ID is a signed 16-bit integer ranges from 0 to 32767.
3. The unit of timestamp looks like nanosecond but to-be confirmed. It's unclear when the time was recorded (namely, at the beginning, end, or in the middle of an event).
