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.
