Impact of the flat-sky approximation on the multipoles of the 2PCF. Top: Curved-sky (solid) vs. flat-sky (dashed) multipoles, with contributions from standard terms (left) and from just lensing magnification (right). Lensing magnification is computed using the values of the local count slope given in Table 2, which are the fiducial values assumed in our analysis. Bottom: Their relative difference in percent, taking the curved-sky case as the reference value.
