Each PFSA file has a W_LGTSRC card, which describes where the spectrograph module light comes from. The choices are currently "sunss", "dcb", "pfi". It would be useful to have that available in the butler registry.
Note that we have no design for the observing mode where the two gang connectors come from different light sources. I think I'd vote for composite strings like "dcb/sunss" or "dcb,pfi" over a separate keyword W_LGTSR2.
