| 6 | Maximum angular deviation | MAD | deg | Acton, Gary D | MAD Free: The maximum angular deviation (MAD) from PCA using the FREE option | |
| 7 | Inclination | Incl | deg | Acton, Gary D | Inclination Anchored: The inclination estimated from principal component analysis (PCA) using the Anchored (ANC) option of PCA, where the line fit through the demagnetization data is anchored to the origin of orthogonal vector demagnetization plots | |
