These tables are formatted as
follows. Each table contains the estimated uncertainties for the cross-coupled
generalized structure coefficients at a single structural degree s. Each
row of each table contains the uncertainty estimates for a pair of multiplets.
Cross-coupled structure coefficients can be either of even or odd degree
depending on the differenece in harmonic degree of the two coupling multiplets
and the two mode types.
The first 6 columns specify
the n, type, and l of the pair of coupled multiplets and the final 2s+1
columns specify the degree s uncertainties.
n1 s1/t1 l1 n2 s2/t2
l2 cerr1 cerr2 cerr3 ...... cerr(2s+1)
The uncertainties are normalized
relative to fully normalized complex spherical harmonics (e.g, Edmonds,
1960) which are commonly used in normal mode studies (e.g., Woodhouse,
1980). For example, for degree 2 there are 5 coefficients: c20, Re c21,
Im c21, Re c22, Im c22. For degree 4 there are 9 coefficients, etc. The
units of the uncertainties are micro-Hz.

structure coefficients can be found by clicking the following: 1,
