When importing RAOs from a text file, the following strings can be used in the header line.
| Header string |
Column contains |
| WP |
Wave period in seconds |
| WFH |
Wave frequency in hertz |
| WFR |
Angular wave frequency in radians/second |
| XA |
Surge amplitude |
| XP |
Surge phase |
| YA |
Sway amplitude |
| YP |
Sway phase |
| ZA |
Heave amplitude |
| ZP |
Heave phase |
| RXA |
Roll amplitude |
| RXP |
Roll phase |
| RYA |
Pitch amplitude |
| RYP |
