Sérsic parameters and their adopted value ranges for the injected sources.
| Parameter | Symbol | Extraction description |
|---|---|---|
| Coordinate (source plane) | ys | Extracted within a buffer around the caustic (width 0.5 re) |
| Source magnitude | mF814W | Sampled from PDF, p(i), COSMOS + HST fields |
| Source redshift | zs | Sampled from PDF, p(z|Δi), COSMOS |
| Effective radius | Re | Re = 2.54 kpc, z ≤ 1 |
| Re(z) = B(1 + z)β, z > 1 (Shibuya et al. 2015) | ||
| Sérsic index | n | Extracted within (1.0, 2.0) |
| Axis ratio | q | Extracted within (0.2, 1.0) |
| Position angle | φ | Extracted within (0, π) |
