Calibration of the lightchains 2020R11 and 2020R12. (a) shows the variability of all sensors on lightchain 2020R11, derived as deviation from the median and the selected calibration timespan (green). (b) shows the absolute calibration of lightchain 2020R11 by comparing derived PAR with PAR derived from the reference RAMSES sensor. (c,d) include the calibration coefficients for lightchain 2020R11 and 2020R12.
