The chan_header and time_header contain duplicate fields which I have thought to be identical. The origin of the D/M suffix was taken over from the wfm_viewer project.

There is a difference in those though: The *M type variables contain the scale and offset information during capture - while the *D variables are the current settings used for display.

So in this context M means _M_easured and D means _D_isplayed.

It might be interesting to calculate offset variables of the saved displayed scaling to the measured scaling. But for now it is best displayed as measured, I think.
