- Collett produced the parameter chains to combine the results with the cosmic microwave background to make inference on cosmological models beyond LCDM (shown in figures 6 and 7). Collett codesigned the observing strategy for the line of sight lensing correction, based on his analysis of which galaxies produce the most significant perturbations in cosmological simulations. The follow up of these galaxies yielded a 0.4% shift on the inferred Hubble constant with a 2.5% uncertainty. Collett suggested systematics tests for the lens modelling and line of sight reconstruction.
