Extended Data Fig. 4: Relative precision in the measurement of Spergel index ν and apparent axis ratio q.
From: In situ spheroid formation in distant submillimetre-bright galaxies
a, The uncertainty σν is a measure of the accuracy of the recovered ν in Monte Carlo simulation, evaluated as the MAD of the data around the true value (σ = 1.48 × MAD). The dashed line represents the best-fit linear relationship between σν and ν and the shaded region indicates the 1σ confidence interval. b, Similar to panel a but showing the uncertainty in q measurement.
