Hi Luca,

The error data is indeed recalculated as part of the binning and would be reduced when more points are combined (you can see it when you plot the error bars). You would need to save the binned data back into the measurements table to see the binned time, flux, and error numerically. Use the "New Col" button to save the binned data as new columns in the measurements table when the data are plotted and binned as you want them:
