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

| Correction Type | RT | DM |
|---|---|---|
| 0 | No correction required - auto-correcting | |
| 1 | P-SP(n) | P-SP(n+1) |
| 2 | no correction required | no correction normally but sometimes warranted |
| 3 | no correction required | no correction normally but sometimes required due to 40dbar limit on autocorrection |
Truncating: a type which truncated SP
SP Adjust (dbar): eg 5 (dbar) for many Apex floats
