| Ωb, 0 | 24% | 13% | 16% |
| w0 | 34% | 14% | 21% |
| wa | 35% | 17% | 20% |
| h | 14% | −8% | 13% |
| ns | 32% | −22% | 9% |
| σ8 | 18% | −21% | 18% |
Notes. The relative difference, 1 − σmagn/σdens, in percentage, is shown for three cases: (a) an optimistic scenario, when the local count slope is measured with high accuracy and thus s(z) is kept fixed in the analysis (Col. 2), (b) a pessimistic scenario where the local count slope cannot be constrained by an independent measurement, and therefore we marginalise over its values (Col. 3), and (c) a realistic scenario such that the local count slope is assumed to be measured independently with a 10% precision (Col. 4). The results reported here refer to our baseline cosmology, the w0 waCDM model.
