Meeting (08012026)¶

We reviewed data to be corrected:

first_event, first_event_time, last_event,last_event_time : seems to be wrong. Fleg will open a ticket so Lech will be able to correct it in gtot
event_type: Always 0 which correspond to shower/standard trigger. Should be 0x1000 for 10s trigger, 0x8000 for random trigger and 0x0000 for shower/standard trigger. Bohao will check/correct
event_version: No clear definition ? Bohao will check.
origin_geoid: Should be the RTK position of the first Antenna. For now it's hardcoded in gtot. It should be added in the binary files by the CS-DAQ. Bohao , Lech and Fleg will see that (because it should be linked with the du_naming process)
du_id, du_geoid, du_xyz, du_type, du_tilt, du_ground_tilt: We decided that this will contains the parameters of all the DUs which are up in the run. This should be strongly linked with the du naming process (because all up DUs will send their position and get their du_id at the beginning of the run). Thus Bohao and Fleg will integrate this point in the du naming process. Lech will be involved because for now this is hardcoded in gtot thus it will have to be modified.

trigger_position: We decided that this parameter should be the position of the first T1 crossing in the time window. As it depends on the trigger parameters it should be calculated from the trigger parameters. Bohao will investigate the best way to perform that.
firmware_version: This should come from binary files. Bohao and Xushin will check that a proper mechanism to tag and follow the updates of the DAQ firmware exists.
gain_correction_ch: Read from the hardware. Should come from TADC. Bohao will check if values are correct or not.
notch_filters_no_ch: Not implemented now. Need to be and it's a priority (needed by analysis). Bohao will implement it.

Next meeting is on friday 16 at 9h00.
