data processing *<br />
The <strong>WCC</strong> acquisition system, which was used for the audit, consists of a 16 channel ADC circuit<br />
board and a PC with the corresponding software. Hooked up to the analog output of all the<br />
instruments involved the data was collected by the data acquisition system of the <strong>WCC</strong>. In<br />
advance, it was checked that the readings of the two acquisition systems were equal at zero<br />
(ozone) and at 200 ppb ozone. For data interpretation the <strong>WCC</strong> data is used.<br />
