I am interesting in recreating the tutorial on summing POP beams coherently in python, has anyone tried this ?

Is there an equivalent ZBFSUM commant for python ?

The attachments given in the tutorial donot contain the full code file, therefore I could use some help on the revelant commands in python ? 

Is writing a macro more suitable for this task ?
