The path from the original idea to observe a target to the value-added data delivered by APIS is long and complex, and involves a significant work from many persons and services such as : the principal investigators for requesting and programming the observations, the conceivers of observing instruments, the engineering teams of space agencies for operating the telescopes and collecting the data, the Space Telescope Science Institute (STSci) and the ESA Hubble Science Archive (ESAC) for calibrating and archiving raw HST data and developing interactive tools for spectra (Specview), the JAXA archive for delivering raw Hisaki data and japanese colleagues for processing them, the Institut de Mécanique Céleste et de Calcul des Ephémérides (IMCCE, Observatoire de Paris) for providing planetary ephemeris, the University of Iowa for providing ephemeris of the Cassini and Galileo spacecraft and finally the APIS team for developing this service.
