Data Set Overview : This data set contains all the infrared polarimetry data archived as part of the International Halley Watch (IHW) Infrared Studies Network (IRSN). Data span the period 21 Sep 1985 to 1 June 1986. The data are presented as separate tables for each set of observations from an observer on a single night. Modification History : As part of the IHW restoration effort, the original data were reformatted, but not otherwise changed. The reformatting process included: o Converting FITS ASCII TABLE extensions into flat ASCII files (i.e., with carriage-control and without blank padding). o Writing new PDS labels whic incorporate all information in the original FITS header, including comments and history notes. o Deleting the original, detached FITS headers. In addition, known errata were corrected, including both the errata noted by Mikael Aronsson at JPL as he prapared the IHW Printed Archive and Printed Archive Index documents (and included on the HAL_0023 volume), and the errata collected after publication at the PDS Small Bodies Node. General Notes : Times ----- The observation times were reported as day fractions with anywhere from one to five decimal places of precision. These have been converted to the ISO standard format (YYYY-MM-DDThh:mm:ss) to a corrsponding level of accuracy. System Codes ------------ The IHW directives for the SYSTEM keyword in the original FITS files mandated a format of 'dooottii', where d : discipline, ooo : IAU observatory code, tt : country code, and ii : (optional) telescope/instrument number assigned by the Infrared Studies Network. For observatories that did not have an IAU code, ooo : 500 and in most of these cases ii : 00. Thus, all U.S. observatories without and IAU code will have SYSTEM : '25001600' in their IRSN contributions. 23 August 2006, A.C.Raugh
