The CCF for the NIRPS spectrum of NGTS-EB-8 from the night of 2023 April 27 cross-correlated with the NIRPS M2 mask. The solid blue line shows the CCF. The vertical dashed–dotted pink line shows the barycentric Earth radial velocity (BERV) value that coincides with the sky emission peak. The orange and green dashed lines show the Gaussian fits for the primary and secondary component, respectively.
