Proper calibration depends on the data itself and user specific judgments. There are many issues to address when analyzing the ASPERA-3 IMA data. The IMA_CALIBRATION_REPORT.PDF (in the DOCUMENT directory) addresses these issues and it is advised to contact the IMA team (Rickard Lundin - rickard@irf.se, Stas Barabash - stas@irf.se, and Andrei Fedorov - Andrei.Fedorov@cesr.fr) for guidance in analyzing IMA data. ** Please contact the ASPERA-3 IMA Team (Rickard Lundin - rickard@irf.se, Stas Barabash - stas@irf.se, Andrei Fedorov - Andrei.Fedorov@cesr.fr) for more information before using IMA data. ********************************** END NOTE ********************************** Additional Information in the DOCUMENT Directory: Although PDS requires documents in the DOCUMENT directory to have an ASCII form, there are several documents in PDF format only: 1. ASPERA3_FLIGHT_PERF.PDF - The ASPERA-3 Flight Performance Report Document (submitted to ESA) 2. ASPERA3_MEX_EXP.PDF - The Analyzer of Space Plasmas and Energetic Atoms (ASPERA-3) for the Mars Express Mission (Draft of ESA Publication) 3. ASPERA3_SENSOR_FRAMES.PDF - The ASPERA-3 Sensor Numbering and frames support document. 4. ME_ASP_DS_0002.PDF - The ASPERA-3 Design Description document. 5. ME_ASP_MA_0003_V3_0.PDF - The ASPERA-3 Flight Operation Manual. 6. IMA_CALIBRATION_REPORT.PDF - The ASPERA-3 Ion Mass Analyzer (IMA) Calibration Report. These documents add to the understanding of the ASPERA-3 experiment, but are considered non-critical for understanding the contents and usage of the ASPERA-3 archived data sets. All critical information for understanding the contents and usage of the ASPERA-3 archived data sets are included in the Catalog files, data labels, or some other ASCII form.
