The value of m is calculated for the operating conditions in each particular flight track. The precision of the RO2* determination is expressed as a standard deviation (std) which is estimated from the signal stability over 2 minutes. Data points with standard deviation of the detector cell pressure > 2 mbar in 1 minute are flagged with P_flag = 1. These points are subject to higher uncertainty as result of changes in the total light extinction in the detector associated with the pressure variation. Each individual flagged period requires further analysis to improve the precision. The RO2* detection limit depends on the operating conditions and is estimated for each individual flight. Data points below the lower limit of detection are flagged by LOD_flag = 1. 1 Time(s) RO2*(pptv) std(pptv) P_flag LOD_flag 38040 162.55 87.30 1 0 38100 34.82 64.00 1 0 38160 46.16 7.49 0 0 38220 11.86
