NO PUBLICATION OR PUBLIC PRESENTATION SHALL BE MADE WITHOUT THE EXPLICIT WRITTEN APPROVAL OF THE SPEDE PI. Introduction ____________ This PDS data archive contains data measured by SPEDE (Spacecraft Potential, Electron and Dust Experiment) instrument onboard SMART-1 spacecraft during spacecraft orbits 15-204. The main task during these orbits was Electric Propulsion monitoring. NOTE! You need also product S1_EP_THRUST_LOG.TAB from the dataset S1-L-ESOC-6-AUXILIARY-DATA-V1.0 to correctly interpret SPEDE data. More information in SPEDESIS document. In addition to science data, this archive contains instrument configuration data, and documentation describing the instrument and the data products. SPEDE data in this archive has been provided by Finnish Meteorological Institute, P.O.Box 503, 00101 Helsinki, Finland. The instrument's PI is Anssi Malkki (Anssi.Malkki@fmi.fi). Disk format ___________ To be added by SMART-1 PDS team. File formats ____________ Data product files in this data archive are of ASCII format. Data products are TABLEs. Documentation files are either ASCII of PDF files. SPEDE data products use attached labels. The labels point to external format containers (*.FMT files), saved in LABEL subdirectory of this archive, and also in all directories containing data products. The *.FMT files must be in data product subdirectores, because not all PDS tools can find them from the LABEL directory if the labels themselves are not there. Data structure is described in SPEDE SIS document, SPEDESIS.ASC, that can be found in DOCUMENT subdirectory.
