Mode data sets: Torodial modes frequency, Q, and splitting coefficients
Center frequencies f, quality factors Q, and degree 2
splitting function coefficients for the 11 toroidal
modes used in this study.
For each mode the first row contains the results for a starting
model that consists of rotation and ellipticity plus SKS12WM13,
and the second row lists the associated standard deviations;
these are the results used to produce Figures 2 and 3.
To demonstrate that the splitting coefficients are reasonably
robust,
we list the results for a starting model that consists
of rotation and ellipticity only in the third row.
The fact that we have roughly half as many recordings for modes
0T4 and 0T5 as we do for the other modes is reflected
in the relatively poor agreement between the splitting coefficients
obtained for the different starting models.
The tabulated coefficients Ast and Bst are related to the
complex splitting
function coefficients cst defined by
for t>0,
for t=0,
and , for t<0
(Li et al., 1991).
The center frequencies are listed in Hz and
the coefficients are listed in unit of 10-6.
