|Target version:||Candidate for next bugfix release|
Running gmt 5.4.0 on ubuntu 16.04.
I'm generating grids with sph2grd, for example with L=10, M=5, C=1, S=0. When setting the normalistaion flag to -Ng, I get grids who's inner products sum to 4*pi. However, when the flag is -Nm, they appear to sum to 0.5 rather than 1.

Would you mind showing how you computed the 0.5 so I can make a test script for this. I am looking at the code and find
plm[mm] = pmm * 0.5 / d_sqrt(M_PI);
so that 0.5 is suspicious in light of your post. But I'd like to verify first.
