Introduction This DVD-R contains Magellan F-BIDR (Full-Resolution Basic Image Data Record) products, including image and data files. These products have been superceded by subsequent versions written to CD-WO. Refer to the CUMINDEX.TAB for a listing of Magellan products and archive volume IDs. Each F-BIDR product contains the full-resolution radar return for one orbit and the ancillary files necessary to understand the data. The F-BIDR products archived on this volume are the exact products released by the Magellan Project. Errors and anomalies are noted where detected. Supporting documentation and label files conform to the Planetary Data System (PDS) Standards, Version 3.0, Jet Propulsion Laboratory (JPL) document JPL D-7669. 2. Disc Format The disc has been formatted so that a variety of computer systems (e.g. IBM PC, Macintosh, Sun) may access the data. Specifically, it is formatted according to the ISO 9660 level 1 Interchange Standard. For further information, refer to the ISO 9660 Standard Document: RF# ISO 9660-1988, 15 April 1988. 3. File Formats Each orbit for which F-BIDR data exists is represented by a set of 20 files. In addition, indices to the image files have been added for each F-BIDR. The files are: ERR_oooo.TXT - List of errors encountered during the tape transfer process FILE_01. - Summary BIDR Volume Information FILE_02. - Orbit Header FILE_03. - EDR Data Quality Summary FILE_04. - S/C ephemeris file FILE_05. - SCLK/SCET conversion coefficients FILE_06. - DSN monitor records FILE_07. - Quaternion pointing coefficients FILE_08. - Processing bandwidth FILE_09. - Decommutation and decalibration data FILE_10. - Engineering data FILE_11. - Radar burst header records FILE_12. - Per-Orbit Parameters FILE_13. - Image data in oblique sinusoidal projection FILE_14. - Processing parameters for oblique sinusoidal data FILE_15. - Image data in sinusoidal projection FILE_16. - Processing parameters for sinusoidal data FILE_17. - Processed radiometric data FILE_18. - Cold-sky calibration results FILE_19. - Processing monitor record FILE_20. - Additional BIDR volume information Further information on F-BIDR file formats and contents can be obtained from the Magellan Software Interface Specification document SDPS-101, Revision E, August 31, 1992. A copy of this document may be obtained from the Magellan Data Product User Support Office (contact information is given in section 6 of this document). All document files and detached label files contain 80-byte fixed-length records, with a carriage return character (ASCII 13) in the 79th byte and a line feed character (ASCII 10) in the 80th byte. This allows the files to be read by the MacOS, DOS, Unix, and VMS operating systems. The PDS label file has the same name as the data file it describes, with the extension .LBL. PDS labels are object-oriented. The object to which the label refers (e.g. IMAGE, TABLE, etc.) is denoted by a statement of the form: ^object = location in which the carat character (^, also called a pointer in this context) indicates that the object starts at the given location. For an object embedded in a label, the location is an integer representing the starting record number of the object (the first record in the file is record 1). For an object located elsewhere, the location denotes the name of the file containing the object, along with the starting record or byte number. For example: ^IMAGE = ("C102.IMG",3) indicates that the IMAGE object begins at record 3 of the file C102.IMG, in the same directory as the detached label file. Below is a list of the possible formats that use the ^object keyword. ^object = n ^object = n ^object = ("filename.ext",n) ^object = ("[dirlist]filename.ext",n) ^object = ("filename.ext",n) ^object = ("[dirlist]filename.ext",n) where n is the starting record or byte number of the object, counting from the beginning of the file (record 1, byte 1); default is record number. indicates that the number given is in units of bytes. filename is the upper-case file name. ext is the upper-case file extension. dirlist is a period-delimited path-list of parent directories, in upper case, that specifies the object file directory (used only when the object is not in the same directory as the label file). 4. CD-ROM Contents The files on this CD-ROM are organized in one top-level directory with several subdirectories. The following table shows the structure and content of these directories. In the table, directory names are enclosed in square brackets ([]), upper-case letters indicate an actual directory or file name, and lower-case letters indicate the general form of a set of directory or file names.
