I turn now to some details. The scorecard in Table 2 shows three parameter choices. In the Einstein-de Sitter case the density parameter is m = 1 and space curvature and the cosmological constant are negligibly small. The second case has zero space curvature and positive , the third negligibly small and negative space curvature. A passing grade () means the measurements are consistent with the parameters within the Friedmann-Lemaître model, a negative grade (X) that there seems to be a significant inconsistency. The greater the number of question marks the greater the level of doubt about the grade.
