***** File ACKNWLDG.TXT ACKNOWLEDGEMENTS These Acknowledgements are concerned with the final steps of CD-ROM preparation and production, steps which were largely taken by a handful of individuals at the NASA/Goddard Space Flight Center, working in collaboration with the Small Bodies Node (SBN) of the Planetary Data System. The simple truth is that if the goal is to create a useful archive, one that is replete with searchable indices, tables of interest, software, and lucid documentation, and, moreover, one which possesses a useful and efficient directory layout (or "CDTREE"), then a very large amount of effort is required. It probably comes as no surprise to the reader that many revisions of plan are encountered along the way, as a scheme which once seemed promising now looks like the course NOT to follow. Once the entire IHW dataset had been transferred and was on-line at the Small Bodies Node (SBN) of the Planetary Data System (PDS) it was possible to complete the set with the help of Dan Klinglesmith and Mal Niedner in the Laboratory for Astronomy and Solar Physics. This brings the story nearly up-to-date (i.e., December 1993). In the last 24 months a great deal of work has been expended at NASA/GSFC (in collaboration with the SBN) to perform the following tasks: o reviewing and revising the layout of the space disks; o responding to calls by the Discipline Specialists for error correction of headers and data (hundreds of files across several of the disciplines), made possible by the headers/data being "on-line"; o creating searchable, delimited tables and indices from on-line headers and data; o generating PDS labels for all datafiles; o writing/editing of documentation to allow the archive user to understand the disc contents and layout; and o frequent checking of procedures and products. o responding to the SBN Peer Review of the Remote Data CD-ROMs by incorporating some simplifying design changes The above should be considered a partial list of the activities which occurred after the IHW data were deposited on the NSSDC Publisher in the late-summer of 1992. If it is appropriate to single out a particular individual within the last 8-12 months, then that person surely is Dan Klinglesmith, who has been extremely active in planning the work. This also includes efforts from Mal Niedner to work through the GSFC contract to get the final volumes produced Data preparation for the last series of IHW CD-ROMs (25 and 26), that of the "Spacecraft Data", is now complete at the SBN, University of Maryland, under the direction of Ed Grayzeck and Mike A'Hearn. We would like to acknowledge individual efforts in this preparation: Mikael Aronsson for collecting and standardizing the original submissions Eric Beach for data preparation at the NSSDC Publisher Phil Esterle who worked to solve the processing steps for the TVS submission Lori Fenton became the editor of the ESA digitized documents Ann Farny at PDS-Central Node who digitized the ESA documents Joe King and Jordan Gottlieb for maintaining the NSSDC Publisher Anne Raugh for reformatting datasets such as PIA and preparing labels Kaly Rengaranjan, Rosana Borgen, Terri Anderson (PDS-CN) for reviewing labels Don Sawyer and Doug Gross for assistance with SFDU work Archie Warnock for his FITS2PDS translator program and general advice
