Confidence regions in the (q0−j0) plane, as provided by Cosmography Ib and II. The inner brown region defines the 2σ confidence level. The parameters q0 and j0 are well constrained, the values q0> 0 are ruled out, the value j0 = 1 (which is the ΛCDM value) is statistically not favorable. On the axes we also plot the box-and-whisker diagrams for the respective parameters: the bottom and top of the diagrams are the 25th and 75th percentile (the lower and upper quartiles, respectively), and the band near the middle of the box is the median.
