Here's my HB/HA spectra taken last night of this interesting quadruple system:

It was very hard to keep the B&C pair off A, I eventually gave-up and just had to "exclude"
Bet B&C Mon off the HA & HB spectra. I did my best with line calibration, but the HB and HA
reference lines don't exactly match the HB & HA peaks.
