Contributions

All authors played a substantial role in one or more of the following: developing the original proposal, managing the project, defining the target list and observation plan, analysing the data, theoretical modelling or preparaing this paper. Some specific contributions are listed as follows. N.B., J.L.B., Z.K.B-T., I.J.M.C., J.M.D., L.K., M.L., D.K.S., K.B.S. and H.R.W provided overall programme leadership and management. D.K.S., E.M.-R.K., H.R.W., I.J.M.C., J.L.B., K.B.S., L.K., M.L.-M., M.L., N.M.B., V.P. and Z.K.B.-T. made substantial contributions to the design of the programme. K.B.S. generated the observing plan with input from the team. B.B., E.M.R.K., H.R.W., I.J.M.C., J.L.B., L.K., M.L.-M., M.L., N.M.B. and Z.K.B.-T. led or co-led working groups or contributed to substantial strategic planning efforts, such as the design and implementation of the prelaunch data challenges. A.L.C., D.K.S., E.S., N.E., N.P.G. and V.P. generated the simulated data for the prelaunch testing of the methods. A.L.C. and E.M.M. co-led the data synthesis effort, light curve generation, spectroscopic light curve fitting, limb-darkening investigation, saturation investigation and production of the planetary spectrum. E.A., L.A., A.D.F., D.G., M.R., Z.R. and K.B.S. contributed substantially to the generation of, and provided, the spectral time series that were used in this paper. N.E., R.B., R.O., G.M. and J.T. performed the white light curve fitting. L.W. and M.L. generated the theoretical model for comparison with the data. A.L.C., E.M.M., N.E. and L.W. made substantial contributions to the writing of this paper. A.L.C. and E.M.M. generated the figures for this paper.
