Notes. A is the absorption depth in ppm, λcentre is the central wavelength of the absorption in nm, σ is the Gaussian width of the absorption in nm, υσ,Gauss is the Gaussian width of the absorption in km s−1, Δυcentre is the offset from the expected centre wavelength in km s−1, σ is the detection significance, calculated from the absorption depth, A, and its uncertainty, and h is the approximate equivalent atmospheric height in units of Rp, calculated as (Pino et al. 2018). We note that this assumes the continuum to be at 1 Rp. The uncertainties in A, λcentre, and σGauss are provided by lmfit. The uncertainties for all other parameters were calculated assuming Gaussian error propagation.
