As far as I know, nuSolve will analyse all data within a vgosDb. Sometimes I have observations covering several days in one vgosDb. In this case, it would be convenient to have one vgosDb, but only analyse say the first day in nuSolve (analysing a sub-timerange separately). I see no way in nuSolve to restrict the timerange of data to include in the solution (except editing out all the non-desired data, but this feels wrong). It would be nice with a selection box to set start/end time for inclusion of data within a vgosDb. It could default to the full observation, as is the current case, and it would not disturb other users in any way. But would be useful for many-day analysis. Now I instead split the observations in separate vgosDbs and analyse each with nuSolve. Works, but even nicer if nuSolve could split on the fly.
