List of Hydra-related papers/talks

Prototyping of Hydra concepts and capabilities is ongoing in a variety of test beds. Here in the table below are examples carried out using prototype code written in IDL --- the "ihy_" and "v3d_" routines in the HAK (HETG Analysis Kit) code. The spectrum and ARF files used by most of these examples are given for reference in:
