Notes. The results are normalized to the FoM of the fiducial sample with mVIS < 24.5. For reference, the unnormalized value of our fiducial sample is 713 for GCph and 411 for GCph + GGL. Galaxy bias and intrinsic alignments nuisance parameters are free in the latter, which provides a lower FoM than in GCph alone.
