gptarget usage

Hi Marc,

I was wondering if there's a possibility to add weights to a measurement point of the dispersion curve (as you can do in the dinver interface) without directly adding the xml file.
I couldn't find anything on that in the gptarget help.

Cheers,
Yannik

Currently gptarget has a rather simple interface, list, add, remove dispersion curves. Adding an option for changing the weight is straight forward.

One precision, do you make reference to the global weight of the dispersion curve misfit compared to the misfits of autocorrelations, ellipticity, refraction,...? Or the individual weights of each dispersion sample? These weights are only used when averaging curves. There are disregarded when computing the misfit. With gptarget, the samples with 0 weights are considered as invalid (see -h).

A -weight option has just been added for next release to set the misfit weight.
Also -min-misfit to setup the minimum misfit.

Thanks for that.
