K(LDRCal) is the variability of K depending on LDRCal. If LDRCal is not known, its uncertainty has to be included in the input file for the error calcualtion below. LDR_min-true(LDR_true) and LDR_max-true(LDR_true) are the difference between the lowest and highest possible retrieved LDR, respectively, and the true LDR depending on the true LDR. They represent the negative and positive uncertainty of the retrieved LDR resulting from all known uncertainties of the optical input parameters. ----------------------------------------------- 2nd order polyfit = a + (b * LDR) + (c * LDR^2) fit-parameter, K(LDRCal), LDR_min-true(LDRtrue), LDR_max-true(LDRtrue) a, +0.96352, -0.00674, +0.00727 b, +0.06904, -0.02805, +0.03080 c, -0.04188, +0.01659, -0.01587 ################################################################################## Further statistical analyses of the uncertainties, their distribution and sources: LDRtrue , mean , median, max-mean, min-mean, std, excess_kurtosis, skewness 0.00400, 0.00404, 0.00402, 0.00739,-0.00685, 0.00431, -1.37505, 0.01060 0.02000, 0.02004, 0.02003, 0.00788,-0.00729, 0.00432, -1.35168, 0.01361 0.10000, 0.10006, 0.10001, 0.01019,-0.00938, 0.00447, -1.11574, 0.02519 0.30000, 0.30013, 0.30010, 0.01508,-0.01366, 0.00523, -0.47128, 0.06082 0.45000, 0.45018, 0.45000, 0.01792,-0.01600, 0.00607, -0.34137, 0.12718 minimum and maximum values of the distributions of signal ratios and calibration factors for different LDRtrue LDRtrue , LDRsim, (max-min)/2, relerr 0.00400, 0.04596, 0.01325, 0.28826 0.02000, 0.07602, 0.01353, 0.17791 0.10000, 0.21319, 0.01478, 0.06935 0.30000, 0.48224, 0.01725, 0.03578 0.45000, 0.63531, 0.01866, 0.02937 LDRtrue , Etax , (max-min)/2, relerr 0.00400, 0.97066, 0.03207, 0.03304 0.02000, 0.97066, 0.03207, 0.03304 0.10000, 0.97066, 0.03207, 0.03304 0.30000, 0.97066, 0.03207, 0.03304 0.45000, 0.97066, 0.03207, 0.03304 LDRtrue , Etapx , (max-min)/2, relerr 0.00400, 0.97203, 0.03152, 0.03243 0.02000, 0.97203, 0.03152, 0.03243 0.10000, 0.97203, 0.03152, 0.03243 0.30000, 0.97203, 0.03152, 0.03243 0.45000, 0.97203, 0.03152, 0.03243 LDRtrue , Etamx , (max-min)/2, relerr 0.00400, 0.96930, 0.03303, 0.03408 0.02000, 0.96930, 0.03303, 0.03408 0.10000, 0.96930, 0.03303, 0.03408 0.30000, 0.96930, 0.03303, 0.03408 0.45000, 0.96930, 0.03303, 0.03408 LDRCorr: contribution to the total error (per mill) of individual parameter errors of combined parameter errors at LDRtrue 0.004 0.020 0.100 0.300 0.450 0.004 0.020 0.100 0.300 0.450 Qin 725 680 519 318 230 21 19 13 4 0 RotL 34 32 25 15 12 1 1 1 1 1 DiC 15 24 62 133 185 7 8 15 28 37 TP 31 49 104 145 138 9 9 7 3 0 TS 31 49 104 145 138 9 9 7 3 0 RP 141 132 101 62 45 4 4 3 1 0 RS 0 0 0 0 0 0 0 0 0 0 RotaT 0 0 0 0 0 0 0 0 0 0 LDRCal 21 33 84 182 252 10 12 19 34 44 Sum 999 999 999 999 1000 61 62 64 74 83 LDRsim: contribution to the total error (per mill) of individual parameter errors of combined parameter errors at LDRtrue 0.004 0.020 0.100 0.300 0.450 0.004 0.020 0.100 0.300 0.450 Qin 745 706 550 310 202 15 14 11 6 4 RotL 35 33 26 14 9 0 0 0 0 0 DiC 0 0 0 0 0 0 0 0 0 0 TP 68 108 258 425 465 18 17 13 9 9 TS 2 4 30 134 216 1 1 4 8 9 RP 148 143 121 88 73 2 2 2 1 1 RS 3 5 14 28 34 1 1 1 1 1 RotaT 0 0 0 0 0 0 0 0 0 0 LDRCal 0 0 0 0 0 0 0 0 0 0 Sum 1000 1000 1000 1000 1000 37 35 30 26 25 EtaX, D90: contribution to the total error (per mill) of individual parameter errors of combined parameter errors at LDRtrue 0.004 0.020 0.100 0.300 0.450 0.004 0.020 0.100 0.300 0.450 Qin 10 10 10 10 10 3 3 3 3 3 RotL 0 0 0 0 0 0 0 0 0 0 DiC 136 136 136 136 136 24 24 24 24 24 TP 312 312 312 312 312 7 7 7 7 7 TS 294 294 294 294 294 13 13 13 13 13 RP 32 32 32 32 32 0 0 0 0 0 RS 30 30 30 30 30 1 1 1 1 1 RotaT 0 0 0 0 0 0 0 0 0 0 LDRCal 186 186 186 186 186 29 29 29 29 29 Sum 1000 1000 1000 1000 1000 78 78 78 78 78 Etapx, +45°: contribution to the total error (per mill) of individual parameter errors of combined parameter errors at LDRtrue 0.004 0.020 0.100 0.300 0.450 0.004 0.020 0.100 0.300 0.450 Qin 9 9 9 9 9 3 3 3 3 3 RotL 6 6 6 6 6 3 3 3 3 3 DiC 132 132 132 132 132 23 23 23 23 23 TP 317 317 317 317 317 7 7 7 7 7 TS 300 300 300 300 300 13 13 13 13 13 RP 33 33 33 33 33 0 0 0 0 0 RS 31 31 31 31 31 1 1 1 1 1 RotaT 0 0 0 0 0 0 0 0 0 0 LDRCal 172 172 172 172 172 28 28 28 28 28 Sum 1000 1000 1000 1000 1000 79 79 79 79 79 Etamx -45°: contribution to the total error (per mill) of individual parameter errors of combined parameter errors at LDRtrue 0.004 0.020 0.100 0.300 0.450 0.004 0.020 0.100 0.300 0.450 Qin 10 10 10 10 10 4 4 4 4 4 RotL 6 6 6 6 6 4 4 4 4 4 DiC 139 139 139 139 139 27 27 27 27 27 TP 303 303 303 303 303 7 7 7 7 7 TS 284 284 284 284 284 13 13 13 13 13 RP 31 31 31 31 31 0 0 0 0 0 RS 29 29 29 29 29 1 1 1 1 1 RotaT 0 0 0 0 0 0 0 0 0 0 LDRCal 197 197 197 197 197 33 33 33 33 33 Sum 999 999 999 999 999 89 89 89 89 89
