Introduction This archive contains engineering data of the APXS instrument on ROSETTA. It also contains documentation which describes the APXS experiment. The APXS data archived in this data set are the exact products as described in the APXS Experiment to Archive Interface Document(EAICD), supporting documentation and label files, conform to the Planetary Data System (PDS) Standards, Version 3.6. Additional information about the APXS experiment can be found in documents on ESA's file servers and from the PDS Small bodies Node. 2. Volume format This section is not applicable since the data are stored only electronically. 3. File Formats Tabular files are formatted so that they may be read directly into many database management systems on various computers. All fields are separated by blancks, and character fields are enclosed in double quotation marks ("). Character fields are left justified, and numeric fields are right justified. The last two bytes of each record contain the ASCII carriage return and line feed characters. 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 character (^, also called a pointer in this context) indicates that the object starts at the given location. In a detached label, the location denotes the name of the file containing the object, along with the starting record or byte number. For example: ^TABLE = "MY_TABLE.TAB" indicates that the TABLE object points to the file MY_TABLE.TAB . Pointers to data objects are always required to be located in the same directory as the label file, so the file MY_TABLE.TAB in this example is located in the same directory as the detached label file named MY_TABLE.LBL. Other type of pointer statements is also found in this dataset. ^ STRUCTURE : it is a pointer to the format file (.FMT) describing the data file and located in the LABEL directory 4.
