Binary system parameter ranges.
| Parameter | Range |
|---|---|
| P [yr] | [0.01, 5] |
| a [AU] | [0.1, 10] |
| e | [0, 0.9] |
| q | [0.01, 1] |
| l | [0.01, 1] |
| tperi [yr] | 2016 |
| θv [°] | [−180, 180] |
| φv [°] | [0, 360] |
| ωv [°] | [0, 360] |
Notes. Binary system parameter ranges used to generate mock Gaia astrometric observations. We consider a specific tperi, while the other parameters are generated from random uniform distributions limited by the specific parameter range. The single source parameter ranges and distributions are the same as for microlensing events (see Table 1).
