Table 1.
Overview of the number of free parameters, maximum a posteriori likelihood, and BIC score for different expansion orders for cosmographic models 1, 2, and 3.
| Model 1 | ||||
|---|---|---|---|---|
| Parameter | First order | Second order | Third order | Fourth order |
| Free parameters | 4 | 5 | 6 | 7 |
| lnℒm.a.p. | −60.8 | −55.8 | −55.3 | −55.2 |
| BIC score | 137.2 | 131.1 | 134.1 | 137.8 |
| Model 2 | ||||
| Free parameters | 4 | 5 | 6 | 7 |
| lnℒm.a.p. | −67.1 | −56.8 | −55.7 | −55.0 |
| BIC score | 149.8 | 133.2 | 134.9 | 137.4 |
| Model 3 | ||||
| Parameter | Second order | Third order | Fourth order | Fifth order |
| Free parameters | 4 | 5 | 6 | 7 |
| lnℒm.a.p. | −61.0 | −56.1 | −56.0 | −54.5 |
| BIC score | 137.6 | 131.7 | 135.5 | 136.3 |
Notes. These numbers were calculated using the four lenses, SN, and BAO points and assuming a flat Universe. For expansion in H (models 1 and 2) the second order is preferred, and for expansion in distance (model 3) the third order is preferred. This corresponds to five free parameters in each of the models.
