Thanks, Roberto. I'll take a look at your data - a detailed investigation make take a while, though... After a first brief inspection it seems that * the data from the same instrument, but for different calibration standard can be mapped to each other with virtually no errors. * DTP70 readings can be estimated from DTP70_UV readings (or vice versa) with an estimated error of about 0.1 dE RMS * I1 readings can be estimated from DTP70 or TDP70_UV readings (or vice versa) with an estimated error of about 0.3 dE RMS Best Regards, Gerhard
