Subject:
TMP/AETH/NEPHELOMETER/PASS/PSAP/S1 - Impactor state occasionally incorrect
DataStreams:tmpaospsap3wS1.b1, tmpaosnephdryS1.b1, tmpaosnephwetS1.b1
Description:
The computer controlling the impactor state was rebooting every 15 minutes causing 
periodic gaps in the data and interrupting the normal sequence of states.
Suggestions: 
The impactor state can be determined unambiguously by looking at the dry nephelometer 

pressure.
