Notes:

Type codes: AL = Algol binary; RS = RS CVn binary.

Feature codes:

  1. gas stream (along the predicted gravitational trajector
  2. accretion disk (Keplerian velocities)
  3. accretion annulus (low velocity emission)
  4. stream-star impact region (where gas stream strikes stellar surface)
  5. hot spot (stream-disk impact)
  6. circumprimary emission (centered on mass gainer)
  7. chromosphere (cool secondary star)
  8. absorption zone (region dominated by absorption/hotter gas?)
