Adds wavelength check to direct integration
Adds wavelength check to direct integration

The direct integration had an extraneous line which called
get_observations() even though this task is actually handled in the next
line ny convert_magnitudes_to_fluxes().

I added the wavelength check to convert_ and deleted the extraneous
call to get_obs... and now everything works!
