'aTx=b' is referenced from 'nag-f04.boot.pamphlet' (among others).
For ATX=B.bitmap you are probably right.

ATM we use only few .ps files. However there are many commented out 
references in the axiom book, that is files we should use but
for some reason (problems with flat environment???) we do not use
them now. There is a lot of junk: files that do not show up in
ghostscript at all, files which probably have bogus boundig box,
duplicates. We can easily recreate graphs, screenshots need
more work to recreate and a few files (probably 2 or 3) are
"original artwork". In ideal world sombody would sort the
.ps files into "valuable" (needing some/lot of effort to recreate),
"cache" (the ones which we put in the distribution, but can
easily recreate) and junk. But in short term mass deletion
may be the best solution.

You missed '.eps' endinig:

P28a.eps is very special, because it actually shows in the book :)

> Here is a similar hack for bitmaps:

You missed references from the browser:

> s21bdf1.bitmap

This one is "used":

nag-s.boot.pamphlet:  htInitPage("S21BDF - Symmetrised Elliptic Integral of 3rd
Kind \space{1} \vspace{-28} \inputbitmap{\htbmdir{}/s21bdf1.bitmap}", nil)

I think that finding unused bitmaps need some more work: it seems that
some references to bitmaps appear without file suffix, also because of
quoting rules some names appear mangled.  OTOH I think it is safe bet
that browser do not access '.ps' files from 'src/doc/ps'. First, 
browser do not have support for showing '.ps' files, and while contains (commented out) call to ghostscript it seem to be
the only case. Second, it seems that browser were supposed to access
only files from 'share' subtree and that files from 'src/doc/ps'
were not installed here.
