SGP/SONDE Pressure jump at launch
DataStreams:sgpsondewrpnB6.a0, sgpsondewrpnB6.a1, sgpsondewrpnC1.00
Description:
Sonde pressure at launch recorded as 974.9 (THWAPS 975.1); first pressure after launch 
recorded as 969.7.  This difference is slightly larger than would be expected.  It may be 
that the pressure sensor was jarred during launch or the system failed to detect the 
correct time of launch.  In either case, the absolute altitudes for this sounding will be 
incorrect as will be the ascent rates during the first 30 seconds of flight.
