DATA_INFO: Units are pptv for OH interference. UNCERTAINTY: HOx absolute accuracy ~+/- 32% (actually a multiplicative factor of 1/1.32 to 1.32), 2 sigma confidence. ULOD_FLAG: -7777 ULOD_VALUE: N/A LLOD_FLAG: -8888 LLOD_VALUE: N/A DM_CONTACT_INFO: William H.

OTHER_COMMENTS: Final Data. OH interference signals from individual 20 or 30 second periods have been averaged together for 150 seconds. - This averaging compensates for the noise introduced because OH and OH interference measurements are done sequentially, - and the OH interference signal is the residual of the chemical removal of ambient OH. - Small variations in ambient OH measurements yield large (~1*10^6 cm^-3) variations in individual 20 or 30 second measurements.
