Query: Isolated Prompt Photon Production at HERA   We study the expectations for prompt photon production rates at HERA in a
fully consistent next-to-leading order (NLO) QCD analysis, taking into account
the effects of experimental isolation requirements. In particular we examine
the sensitivity of the isolated cross section to the photon's gluon content.
