Fitting Travel TimesThe purpose of timedistance helioseismology is to calculate the travel time of solar waves between two surface points. The basic way to do this is to calculate the crosscovariance between the signal at the two points. The travel times are measured by fitting wavelets to the crosscovariance. These IDL routines for measuring travel times from cross correlations. Two methods are implemented: a Gaborwavelet fit and a oneparameter fit. Download: Fitting travel times (tar file)
