Hello All,

My question is: any trick to perform a DC DFT from multiple series (after shifting to zero point, eg V passband), for example data from ASAS-SN V, g and SuperWASP ?

Hi Franco

The simplest approach is to select all the series you want to analyse (via Plot Control Dialog) then use View -> Filter from Plot to create a filtered series containing all the data visible in the plot.

Then you can apply DCDFT to the Filter series.
