Subject:
SGP/PSAP/E13 - PSAP data gaps greater than 1 hour due to transmittance less than 0.7
DataStreams:sgpaospsap3wE13.b1, sgpaostapE13.a0, sgpaostapE13.00, sgpaospsaprE13.a0,
sgpaospsap3wE13.00, sgpaospsap3w1sE13.b1, sgpaospsap3wE13.a1, sgpaospsap3w1mE13.b1
Description:
Vendor specifies transmittance must be greater than 0.7 for valid data.  The SGP PSAP 
doesn't include a dilution system so Operators frequently are unable to change filters in 
time.
Suggestions: 
Do not use data
