The request, as written, doesn't make sense.

What do you consider a "light curve"?

And where do you intend total_flux(x) to come from?
I don't think your description of what you're trying to do is workable,
most likely because you've reduced it too far from what you're actually
You'll have to show an actual, complete example. What are those
functions, what do they have to do with the data files, and what is it
you're actually trying to achive?
