At the moment, the `NullInstrument` [note that you mention](https://github.com/iancze/Starfish/blob/master/Starfish/grid_tools.py#L484) is simply a placeholder for functionality that has not yet been implemented. To add this, we would need to find a way to skip the [FFT step](https://github.com/iancze/Starfish/blob/master/Starfish/grid_tools.py#L632) in the `process_flux` routine. \r\n\r\n- [ ] add `NullInstrument` to list of possible instruments\r\n- [ ] modify `HDF5Creator.process_flux` to skip FFT upon `NullInstrument`\r\n\r\n"}}
