This data set contains the infrared images collected and archived by the International Halley Watch (IHW) Infrared Studies Network (IRSN). Raw and calibrated data are included, as well as calibration observations of standard stars. These data have been reformatted and the accompanying documentation updated in this revised version.

This data set contains the polarimetric results reported to the International Halley Watch (IHW) Photometry and Polarimetry Network (PPN) by the various participating observers. Only linear polarizations are reported. Both standard and non-standard broadband and narrowband filters were employed. A total of 752 observations are included spanning the period 13 September 1985 to 17 May 1986.

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 data from the Infrared Polarimetry subnetwork contains 137 observations spanning dates from 1985 September 16 through 1986 June 1.
