Introduction This volume contains the RAW data of the CENA sensor of the SARA inst- rument from the NORMAL PHASE OPERATIONS of the CHANDRAYAAN-1 mission .RAW data means level 2 data on the CODMAC scale, i.e. edited da- ta corrected for telemetry errors, also referred to as Experimental D- ata Record (EDR).Each data product contains all data from one orbit. The data products of CENA sensor of SARA on this volume are the exact products released by the CHANDRAYAAN-1 project. Supporting do- cumentation and file labels conform to the Planetary Data System Standards, Version 3.7,Jet Propulsion Laboratory (JPL) document JPL D- 7669. Information about the CHANDRAYAAN-1 mission, the SARA Experiment, and this dataset can be found in the `CATALOG' and `DOCUMENT' directo- ries. Information on the dataset be found in the `DATASET.CAT' in the `CATALOG' directory. Additional information about the SARA Exper- iment, including the acquisition, processing,and quality of the SARA data can be obtained from Dr. Anil Bhardwaj Space Physics Laboratory Vikram Sarabhai Space Center Trivandrum - 695 022 India Tel: +91 471 2562330 Email: anil_bhardwaj@vssc.gov.in and Dr. Stas Barabash Swedish Institute of Space Physics (IRF) Box 812, SE-981 28 Kiruna, Sweden Tel: +46 980 79122 e-mail: stas@irf.se 2. Volume format The volume is made available online by the Indian Space Research Organisation (ISRO) and by the European Space Agency (ESA). ESA pub- lishes the data via the Planetary Science Archive (PSA) on the world wide web at http://www.rssd.esa.int/psa 3. File format The data is separated into files by orbit. Each data product consists of two files: * An ASCII label file containing a PDS conforming description of the format in which the data are provided and * a file containing the actual data. It is a binary file for a science data product. Each CENA PDS data product file contains an PDS ARRAY of records of CENA measurements in one orbit. Some more details on the file format are given in `DATASET.CAT'. A comprehensive description of the PDS labels is provided in the EAICD in the `DOCUMENT' directory. 4. Volume contents The files in this volume are organized in one top-level directory with several subdirectories. The following table shows the structure and contents of these directories. In the table, directory names are enclosed in square brackets ([]). Upper case letters indicate an actual directory or file name while lower case letters indicate place- holders illustrating the general form of a directory or file name.
