Hi Christophe,

Actually, there is no way to save the binned data at this point. it is on our development to-do list.

There is however an approximation to binning that you can use for now to save a data-averaged set of data points to the measurements table. Instead of using the Out Bin feature, use the "Input Average" feature on Multi-plot Y-data. It is just to the right of the Symbol shape selection. This option combines N number of samples rather than binning over a certain time bucket. For example, if you have 2 sec exposures and want to combine 10 data points to simulate a 20 sec exposure, set the "Input Average" value to 10.

Once you have the lightcurve plotted the way you want it to save, use the "New Col" icon on the left hand side to create the new columns in the measurements table. Then save the measurements table.

You can also output a reduced set of specific columns from the measurements table into a simplified data file using Multi-plot Main > File > Save data subset to file.
