The accretion disk of SS 433?

I discuss two points concerning recent Brackett series spectra of SS 433. The first is that outbursts to red and blue episodic in the Balmer series are now shown to be episodic in the far infrared Brackett series. The second point is that while in quiet times the Brackett profiles are characteristic of a disk rotating at ~ 200 km/s, such a disk is not the accretion disk and it should not be claimed that these profiles require a compact object mass less than 2.2 solar masses.
