robtex phantom data

i've tried asking the robtex folks where they get their as-macro data,
but have not received a response. i'm trying to figure out where they
are getting the as-spiretech as-macro from. i know i created that years
ago, but i can't find it in any of the routing registries i might have
used. i may have forgotten to delete it, but i can't figure out where
it is in order to kill it off. other data in robtex seems to be
current, so it seems likely that they are getting the data from a db
somewhere, but where?

anyone out there have any good ideas of where to look? or if robtex has
a known issue with as-macros?
