These tables are formatted exactly like the structure coefficient tables. Each table contains the uncertainties in the estimated structure coefficients only at a single structural degree s. Each row contains the uncertainty in the even degree self-coupled structure coefficients for a single multiplet. The first 3 columns specify the n, type, and l of the multiplet and the final 2s+1 columns specify the degree s structure coefficient uncertainties.
n s/t l cerr1 cerr2 cerr3 ...... cerr(2s+1)
These 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 coefficient uncertainties: cerr20, Re cerr21, Im cerr21, Re cerr22, Im cerr22. For degree 4 there are 9 coefficients, etc. The units of the uncertatinties are micro-Hz.
A discussion of the structure coefficients can be found by clicking the following: 1, 2, 3. A discussion of normalization is on the second page.
