TSpectrum::SearchHighRes peak finder

Hello all,

we try to use ROOT’s one-dimensional SearchHighRes algorithm to identify signal peaks in raw-data we get from a TDC. The identification of the peaks works pretty well, but the peak positions SearchHighRes returns are only of type integer.
For our analysis it’s necessary to get the peak positions more precisely.
Does anybody know a clever method which does not need much computing time (e.g. avoiding long fitting procedure) to use the SearchHighRes algorithm in a more precise way?

Best regards,
