Subject:
SGP/SONDE - Operator used wrong calibration tape
DataStreams:sgpsondewndcalcB4.c1, sgpsondewrpnB4.a1, sgpsondewrpnB4.00, sgpsondewrpnB4.a0
Description:
It appears that the operator loaded the wrong calibration tape with this
sonde.  All PTU data are incorrect.  Apparently, the operator noticed a
problem and started a new sounding at 0305 (different file).
Suggestions: 
Delete file.
