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.
