Calibration data included:
-------------------------
Calibration data is only included if the subdirectory "cals"
exists with this dataset. It may include "Pre" and "Post"
subdirectories.
It may contain: 
1) "SEAS 2000 Binary XBT Message Type 2" (filename.bin) and/or
2) SIO's ascii representation of the binary file above but
   with 3 digit decimal precision of the temperature (<cruise>r_<TP#>.SRP)
   (This is similar to NOAA's <filename>.NDC)

MetObs:
-------
If MetObs are available, it is included in the main directory
named <cruise>_MetObs.pdf (or jpg)

Data Description:
-----------------

Each cruise dated directory contains "q" files (eg p091509q.051) which
are ascii files containing xbt drop data, and a synopsis data file
(eg p091509.dat) containing position information for each xbt drop.

Note this data set used Sippican Deep Blue XBT's using the
old fall rate coefficients:  a=6.472, b=-2.16


Quality control:
----------------
We followed the CSIRO Marine Lab Report 221 "Quality Control Cookbook for
XBT Data" to mark:

Data Quality Class:
 Class 0 = No QC done
 Class 1 = Good data
 Class 2 = Probably good data
 Class 3 = Probably bad data
 Class 4 = Bad data
 Class 5 = Changed

Data Quality Code: 
 Class 1: EF = Eddy/Front
 Class 1: IV = Inversion confirmed
 Class 1: NU = Inversion in ML (nub confirmed)
 Class 1: ST = Fine structure step-like confirmed

 Class 2: BO = Bowing in ML
 Class 2: FS = Fine Structure Probable
 Class 2: HB = Hit Bottom isotherm boundary layer 
 Class 2: LE = Leakage Possible
 Class 2: PI = Inversion Probable
 Class 2: PL = Premature Launch (false splash)
 Class 2: PS = Fine Structure Step-Like Probable
 Class 2: SA = Surface Anomaly, Fine Structure Special Case
 Class 2: TD = Temperature Difference at Depth
 Class 2: WS = Wire Stretch Possible

 Class 3: HB = Hit Bottom Reject
 Class 3: IP = Insulation Penetration Reject
 Class 3: LE = Leakage Reject
 Class 3: TO = Temperature Offset Reject
 Class 3: WS = Wire Stretch Reject

 Class 4: HF - High Frequency Reject
 Class 4: NG - No Good Profile Reject
 Class 4: SP - Spike Reject
 Class 4: WB - Wire Break Reject
 Class 4: TP - Test Probe Reject

 Class 5: CS = Surface Spike, Start-up transient(Changed)
 Class 5: SP = Spike (Changed)
 Class 5: HF = High Frequency Interference (Changed)
 Class 5: IP = Insulation Penetration (Changed)

Each cruise directory has a <cruise>.dat file.  <cruise> is replaced
by line (p50 or p81) and date (9603, 9606, etc) to get
a filename such as p091509.dat.  An example format of p091509.dat:
