The JSON file for the SiPM pedestals contains, for each SiPM channel (0–1023), the median pedestal values in high gain and low gain, respectively "median_HG" and "median_LG", along with the corresponding width estimates, computed as the interquartile range divided by 1.349, respectively "iqr_eff_HG" and "iqr_eff_LG".

Structure for each channel:

"channel #" : {

"median_HG" : value,

"iqr_eff_HG" : value,

"median_LG" : value,

"iqr_eff_LG" : value,

}

The other 4 JSON files are related to equalisation and calibration of the PMTs. 2 of them contains respectively the scintillating and Cherenkov equalisation coefficients; the other 2 the calibration ones, obtained as the product of the equalisation coefficient for each module and the calibration one for the fiber type.

5 Multiphoton in 2024 and 2025

Speaker: Ruggero Turra (Università degli Studi e INFN Milano (IT))
