It represents the output of the calibration work through all the ISO Post Operations Phase to produce the best automatically calibrated data products for the ISO mission. This release pertains to the data products in the archive: Tuning of the support and explanatory documentation will continue for some more months, and support documentation will undergo occasional upgrades in the coming years of ISO's Active Archive Phase.
Later on, when new version of the Offline Processing Software and Calibration files became available, and on-the-fly processing facility was provided in the ISO Data Archive to allow users to get the most up-to-date ISO products.
On 16/05/2001, the ISO New Interim Archive was released when all ISO telemetry had been reprocessed with OLP 9.1 and CALG 6.0 to produce a complete and uniform set of ISO products. This time, as technology had evolved, all the products were stored directly on magnetic disks which allow faster access.
All icons, postcards and survey products available from the ISO Data Archive applet have also been reprocessed.
Now the on-the-fly reprocessing option has been removed from the IDA interface having become irrelevant. At the same time, the option to receive the products on CDROM has also been removed as all the retrieval requests are now made by FTP.
Furthermore, there will still be regular updates of the ISO Data Archive interface.
