MAG/PSAP/M1 - Impactor not operational
DataStreams:magaospsap3wM1.b1
Description:
All data in this period should be considered to have a 10-um cutoff.  This was confirmed 
by observation of the PSAP flow.

MAG/PSAP/M1 - Impactor state backwards
DataStreams:magaospsap3wM1.b1
Description:
Impactor was installed on 2012-07-12 but did not toggle until 2013-05-16 00:04:19 UTC.

The impactor as delivered did not have limit switches indicating the impactor state. Only 
the command signal was available and is saved in the 'master' data stream. A programming 
error led to the command signal having reverse polarity (1 is actually 10 and 10 is 
actually 1-um cutoff)

MAG/AOS/ALL/M1/S1/S2 - Ship in port
DataStreams:magaospsap3wM1.b1
Description:
The ship was in port during these periods and the measurements may be affected by various 
sources (overhead cranes, anthropogenic sources, etc).

Note: Dates and times were found by looking at the NAV datastream.  The standard deviation 
of pitch, roll, and surge velocity were used to determine when the ship was slowing down 
to enter port or speeding up to leave port.  Thresholds used; pitch (0.01), roll (0.01), 
surge velocity (3.0)
