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

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
