| u | "advection" component of movement; northward component of directed movement | 0 | nm/day |
| v | "advection" component of movement; eastward component of directed movement | 0 | nm/day |
| D | "diffusion" component of movement. A measure of the variability in movement | 100 | nm^2/day |
| bx | systematic error (or bias) in the estimation of position (longitude) | 0 | degree |

| ssst | random error in the estimation of sea-surface temperature, SST | 0.1 | degree Celsius |
| a0 | upper bound for latitude variance (keep the tagged animal in this planet). Used in "solstice" variance structure, related to how the latitude estimation error varies around the equinox. | 0.0001 | degree |
| b0 | the number of days prior to the equinox where the latitude error is maximal. Used in "solstice" variance structure, related to how the latitude estimation error varies around the equinox. | 0 | day |
| r | smoothing radius of SST data; radius centered from a given point within which satellite SST data are used | 200 | nm |
| Option | Usage | Initial value | Unit |
