DATA_SET_DESCRIPTION
Data Set Overview
=================
This data set presents the photometry of comet 1P/Halley
collected by the International Halley Watch (IHW) Infrared
Studies Network (IRSN) over the period September 1984 to
April 1988.  Nearly all files contain magnitude measurements,
although two files of flux measurements are also included.
Version 2 includes data submitted as addenda after the
initial archive generation.
 
The data have undergone substantial reformatting for
Version 2, but none of the original data bytes have
been changed.  Format changes include:
 
  o Incorporating all information from the FITS headers
    into the newly generated PDS labels.
 
  o Calculating accurate START_TIME and STOP_TIME values,
    where sufficient information was available.
 
  o Converting all data files from FITS ASCII tables to
    standard flat ASCII tables (i.e., with carriage control)
    with separate FITS headers.
 
  o Locating and separating the two flux observations from
    the rest of the magnitude files.
 
  o Subdividing the directory containing the magnitude files
    into subdirectories by month of observation.
 
  o Adding three tables of data (47 observations total)
    submitted as addenda to the original archive (and
    archived with the PDS as data set
    EAR-C-IRPHOT-2-RDR-HALLEY-ADDENDA-V1.0) to the data/
    collection in the addenda/ subdirectory.
 
In addition, all reported errata were corrected.
