ValueError: operands could not be broadcast together with shapes (4,) (200710,31,7)

[cress1234]

Using the example exactly as in the documentation with the example files (none of my own input data), I get this error. It is flagging this line

>residual = log_flux - model_fluxes

Here is the whole error message:

Same error pops up for me when I try following the example. What are we doing wrong?

Double-check that the lengths (shapes) of your filter= and aperture= variables match the format of your fitter data file.
