These are recent results of elastic calibration.
"coeff_npsSchm.txt" shows the calibration coefficients calculated using fadc sample amplitude .
The format in this file is the current PMT number:coefficients.
The calculation of calibration coefficients can be found here: https://haohuang.notion.site/Calculation-of-calibration-coefficients-0641473b54a84815836a1c532f8922af?pvs=4 or in Calculation_of_calibration_coefficients.pdf
From the results of the last elastic runs, we found that the unsteady temperature in the calorimeter may affect the light yield of crystals and result in an effect on the calibration coefficients.

This effect has been verified by further studies by comparing the temperature of crystals from the archive and the start time of each elastic run.
