Query: Cataclysmic variables as possible counterparts of ancient Far Eastern
  guest stars   Continuing our efforts to select possible classical nova candidates among Far
Eastern guest stars and to identify them with modern cataclysmic variables
(CVs), we present a search for counterparts in 24 promising areas of the sky
corresponding to ancient observations between 204 BCE and 1690 CE. These areas
have been derived by us in a previous paper. Based on physical entities of the
CVs in our areas and reasonable magnitude limits compatible with the
distribution of known eruption amplitudes of telescopic classical novae, we
present a catalogue of a total of 80 CVs and related targets which could
possibly have caused the historical sightings. This list could potentially be
reduced by additionally discussing further information more vaguely given in
the text. In some cases, we present a detailed discussion of the interpretation
of ancient sources confronting them with properties of the brightest CVs in the
field. In order to estimate whether this list is representative, we discuss the
distribution of CV types in our catalogue of counterparts for the historical
events. Compared to the entire sky, the surface density of most CV subtypes in
our search fields reveals similar values, except for polars and intermediate
polars, i. e. strongly magnetic CVs, for which a significant excess in our
search fields was detected. Finally, we give an outlook towards future research
in this topic, and add in an Appendix a complete atlas of the celestial maps of
all 24 guest star events, displaying the search areas and locations of CVs
within them.
