Speed up improvements of the new SLITRONOMY implementation, compared to the original SLIT code.
| Operation | SLIT | SLITRONOMY | Speedup |
|---|---|---|---|
| Computation of the lensing operator, F | 1.7 s | 6 ms | 300 |
| Lensing of an image, Fx | 200 ms | 450 μs | 4500 |
| Delensing of an image, F⊤y | 400 ms | 120 μs | 3500 |
| Solve for source light, s | ∼16 min | ∼1 s | 1000 |
| Solve for source and lens light, s + gH | ∼2 h | ∼30 s | 240 |
Notes. These numbers are valid for a the typical configuration of 100 × 100 data pixels, with rpix = 2 for source resolution, and Js = 6 starlet scales. It can be for instance the modelling of a strong lens system imaged by HST in F160W band.
