The NASA study suggested that the goals of the IHW should be    the following: advocacy, coordination, standardization, and    an archive of all the data. Indeed the archive was not to    replace the normal interpretation and publication in    technical journals. Rather it was to complement those    publications by establishing a comprehensive database    suitable for further studies requiring reduced but    uninterpreted data from observers.               The Archive of Periodic Comet Halley has been    completed in a CD-ROM or digital version. The comet's    reduced observations belong to one of the following    disciplines or networks:               1. Astrometry.              2. Infrared Studies.              3. Large-Scale Phenomena.              4. Near Nucleus Studies.              5. Photometry and Polarimetry.              6. Radio Studies.              7. Spectroscopy and Spectrophotometry.              8. Amateur Observations.              9. Meteor Studies               The Infrared Studies Network, the Photometry and    Polarimetry Network, the Radio Studies Network, the Amateur    Observations Network and the Meteor Studies Network are    organized into the following subnetworks:               Infrared Studies Subnetworks:              2.1. Infrared Photometry.              2.2. Infrared Polarimetry.              2.3. Infrared Spectroscopy.              2.4. Infrared Imaging.               Photometry and Polarimetry Subnetworks:              5.1. Broadband Photometry.              5.2. Narrowband Photometry.              5.3. Polarimetry.              5.4. Stokes Parameters               Radio Studies Subnetworks:              6.1. Hydroxyl Feature at 18 cm.              6.2. Spectral Line.              6.3. Continuum.              6.4. Occultation.              6.5. Radar               Amateur Observations Subnetworks:              8.1. Visual-Appearance Descriptions.              8.2. Drawings.              8.3. Photographs.              8.4. Spectroscopy               Meteor Studies Subnetworks:              9.1. Radar              9.2. Visual                 The evaluation of submitted observations and    their selection for the Archive has primarily been the    responsibility of the Discipline Specialist Teams in charge    of the networks. To expound the process of evaluation,    reduction, and formatting of the database, each Discipline    Specialist Team has provided network by network, an outline    and a data-organization description of both the digital and    the printed versions of the Archive.
