Pressure correction choices based on SPO parameter name

This analysis was based on GDAC at 22-Feb-2011

The following table records assumptions about the pressure correction treatment for each float, based mainly on the tech file surface pressure offset parameter name.

Glossary

No correction: either the pressure does not need adjustment for SP, or we do not know what adjustment to do.

Correction Type 1:

       RT profiles: P-SP(n)  
       DM profiles: P-SP(n+1)  

Correction Type 2:

       RT profiles: no correction  
       DM profiles: P-(SP(n+1)-SP(n))  

Truncating: a type which truncated SP

SP Adjust (dbar): eg 5 (dbar) for many Apex floats
