Data Set Overview
    =================
    NASA's International Halley Watch has created a Comet Halley
    Archive.   The collection of data spans the full wavelength range as
    submitted by scientists to the IHW. The observations belong to one
    of the following Disciplines: Amateur, Astrometry, Infrared Studies,
    Large-Scale Phenomena, Meteor Studies, Near-Nucleus Studies,
    Photometry and Polarimetry, Radio Studies, and Spectroscopy and
    Spectrophotometry.  The data collected by these nine disciplines
    were augmented by Spacecraft measurements.  The data were submitted
    to IHW, but the evaluation and selection for the Archive has been
    the primary responsibility of the Discipline Specialist Teams for
    each network in cooperation with the Lead Center.  The data from
    the INFRARED PHOTOMETRY Network contains 2204 observations spanning
    dates from 1984 Sep 14 through 1988 Apr 08.
