| fully absorbed as position offset. | ||
| 2 | G-band | Dominant photometric bias signal (Eq. (5)), |
| fit exported in Appendix A for many sources. | ||
| 3 | Astro | First harmonic of astrometric bias signal; |
| dominant signal for other parameter biases. | ||
| 4 | G-band | First harmonic of photometric bias signal. |
| 5 | Astro | Second harmonic of astrometric bias signal. |
| 6 | G-band | Second harmonic of photometric bias signal. |
