For the dome an ellipsoid is used.

My HP67 program and the HP41 version return the same values. OK, the last two results differ in the third decimal.

The paper uses a "different" formula for the slant bottom section and assumes a spherical dome top with a given radius (which is different from the calculated radius). I can reproduce the results for the top section if mý HP41 program is set to assume a spherical dome top and the calculated radius is overwritten by R=78" as assumed in the paper.
