That is because there isn't a universally accepted answer yet.  Some of
these taxa have only been run in the not-yet-printed Gaia paper of mine;
others have yielded more ambiguous answers (in part because the fragmentary
or otherwise less-than-well-known anatomy leaves a lot of "?"s in the data
matrix, in part because they can comfortably fit inside or outside
Maniraptoriformes.

So far only included in the Gaia analysis: unambiguously outside
Maniraptoriformes.

> Deltadromeus?

In various Sereno studies, outside Maniraptoriformes; in my analyses,
possibly in or possibly outside.

> Ornitholestes?

Ditto.  (In the Gaia paper, outside; in the culled analysis I presented at
the Ostrom Symposium, sometimes in and sometimes out).

> Scipionyx?

In my analyses, same as _Ornitholestes_; if memory serves, Norell et al.'s
presentation at the Ostrom Sypmosium placed it outside Maniraptoriformes.

> Bagaraatan?

So far I'm the only one to run it: unambiguously outside.

> Coelurus?

In Gauthier 1986 and Makovicky & Sues inside (a maniraptoran); in the Gaia
paper, outside; in my Ostrom Symposium analysis, ambiguous.

> compsognathids?

In Gauthier 1986 my Gaia paper, and some of my Ostrom Symposium analyses
inside (a maniraptoran); in my other Ostrom Symposium analyses, inside (an
arctometatarsalian); in Sereno's work, Forster et al. 1998 (the _Rahonavis_
paper), my 1994 paper, outside.

That particular issue is still not out.  Gaia will only be found in
discriminating Earth Science libraries (some universities, museums,
geological surveys, etc.). The website for Gaia is:
http://www.naturae.pt/gaia.  When the Theropod Paleobiology volume is
available, the ordering information will be sent out to various fora,
including this one!
