Table 1.
Wasserstein distance measured between the DES Wide reference subset and five comparison samples.
| Sample | Fluxes | Errors | Fluxes + Errors |
|---|---|---|---|
| Balrog Deep | 0.37 | 3.58 | 3.68 |
| Balrog Wide | 0.34 | 1.00 | 1.14 |
| SPT | 0.35 | 1.12 | 1.35 |
| MPT | 0.34 | 0.53 | 0.78 |
| DES Wide’ | 0.31 | 0.37 | 0.61 |
Notes. Wasserstein distance across three feature spaces: fluxes, flux errors, and the combined flux and error space. ‘Balrog Deep’ and ‘Balrog Wide’ correspond to Balrog simulations with deep-like and wide-like noise levels, respectively. ‘SPT’ and ‘MPT’ refer to the transfer methods introduced in Sect. 2. ‘DES Wide’ denotes a second, independent subset of the DES Wide sample, used as a benchmark.
