[CIG-MC] ask about the geoid output of CitcomS

[Shijie Zhong]

Hi Ronghua,

CMB topography is computed and output on the finite element grid, but may not be expanded in terms of spherical harmonics in the same form as surface topography in the geoid file. If you need CMB topography in terms of spherical harmonics, you may need to modify the code yourself.

Subject: [CIG-MC] ask about the geoid output of CitcomS


Hi all,

I have a problem about the geoid output of CitcomS. From the mannual, I knew the meaning of the columns in the ascii geoid file. There are eight columns in the geoid file, including columns of spherical harmonic degrees(l),order(m), cosine term of total geoid(Slm), sine term of total geoid(Clm), cosine term duing to surface topo,sine term duing to surface topo, cosine term duing to internal density variation and sine term duing to internal density variation. But, I found that there weren't cosine and sine terms for the CMB topo. Could anyone explain this to me, please?
Thanks a lot.


Best regards,
Cui Ronghua
