| Abstract: |
In the study of time-distance helioseismology, Gabor wavelets
are fit to time-shifted cross correlations. Five parameters are fit:
amplitude, phase travel time, group travel time, frequency and
frequency width (envelope width). Typically only the phase and
group travel time are analyzed. I discuss preliminary work to
interpret the frequency width.
