observation of Cyg X- |

| 3 did indeed
confirm the presence of |
|||||||||||||||
| Fe K emission in
the spectrum, but |
|||||||||||||||
| indicated that it
was far from the |
|||||||||||||||
| most prominent
feature. |

| * | Liedahl &
Paerels showed that in |
||||||||||||||
| addition to
H-like and He-like line |
|||||||||||||||
| emission from
lower-Z elements, we |
|||||||||||||||
| also see narrow
radiative |
|||||||||||||||
| recombination
continua (RRCs). |
|||||||||||||||
| * | These indicate
that the line emitting |
||||||||||||||
| gas is
photoionized - suspected, but |
|||||||||||||||
| never previously
demonstrated for |
|||||||||||||||
| accretion-powered
sources. |
