[Ifeffit] Is it legitimate to merge transmission data with fluorescence data?

Dear XAFS community members, I have a question concerning data merge. We normally collect XAFS data in both transmission mode and fluorescence mode. We normally have to merge a few scans to enhance signal-to-noise ratio. For one particular sample, I want to know if it is legitimate to merge its transmission scans with its fluorescence scans to improve data quality? I appreciate any input. Regards.
