Re-organized International Halley Watch (IHW) Data Sets
This data set was included as part of the "mixed disks", HAL_0019 to
HAL_0023. There are no actual data in this data set - it exists to
document data submitted to the Large-Scale Phenomena Network that
for reasons of quality or time could not be digitized for archiving.
See the IHW-C-LSPN-2-DIDR-HALLEY-V1.0 data set and any later versions
for the digitized data.
The data were archived under a fairly early form of the PDS
Standards, and formatted to an equally early form of the FITS
standard, where appropriate, resulting in some particularly arcane
formats for the modern user - including PDS labels with deprecated
terminology and almost no metadata, a FITS headers which refer to an
extension type of 'COMPRESS' that was never formally adopted into the
standard and no longer exists even as a conforming extension.
The reorganization effort sought to separate the data files constituting
the unique data sets into a more contemporary, single-data-set-per-volume
format for ease of access and distribution.
The data files and most supporting files are presented here in their
original format, problematic though that might be. Users interested in
analyzing the data would probably do well to inquire of the PDS or the
Small Bodies Node for version 2.0 of the observational data set.
