Subject:	ASI/CO-ANALYZER/M1 - Reprocess: valve position fields incorrect
Affected Datastreams:	asiaoscoM1.a1
Description	A bug in the a1- and b1-level AOS CO ingest processes caused the valve position fields to be incorrect. This had the trickle-down effect of flagging the primary fields as incorrect via embedded QC in the b1-level product. Reprocessing is being requested now that this ingest bug has been corrected.
