DATA_SET_DESCRIPTION
Data Set Overview
    =================
    NASA's International Halley Watch (IHW) 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 Amateur Observation Network
    archived 11641 measurements of Halley's comet. Even though
    most observers adhered to guidelines established by the IHW,
    visual magnitudes are highly subjective depending on the
    technique of each observer and may vary with the quality of
    the instrument used (e.g., binoculars vs. telescope). These
    magnitude estimates cover the date range from 1985 January
    23 through 1988 February 23.
