Spherical/zonal harmonics library

I've been testing RotateSH function for rotating spherical harmonics in gaussian splatting content. And as far as I can tell, the sh1
in RotateSH
function needs some sign flips to work correctly, i.e. it should be like
#ifdef VL_ROW_ORIENT
// for row vectors, v' = v M
float sh1[3][3] =
{
orient(1, 1), -orient(2, 1), orient(0, 1),
-orient(1, 2), orient(2, 2), -orient(0, 2),
orient(1, 0), -orient(2, 0), orient(0, 0)
};
#else
// for column vectors, v' = M v
float sh1[3][3] =
{
orient(1, 1), -orient(1, 2), orient(1, 0),
-orient(2, 1), orient(2, 2), -orient(2, 0),
orient(0, 1), -orient(0, 2), orient(0, 0)
};
#endif
Is my understanding wrong, or does that depend on some other factors like coordinate axes conventions etc.?
