Overview ------------ This volume contains PSA Level 1B data products from observations acquired with the SOIR channel of SPICAV (Spectroscopy for the Investigation of the Characteristics of the Atmosphere of Venus)on Venus Express VEX). For a complete description of the data products, the user is referred to the DOCUMENT/EAICD text on the archive volume. In the DATA directory, data are stored in subdirectories per observation in files with detached label. Naming of the subdirectories is as follows : YYYYMMDD_Maa_Obb with YYYY=year, MM=month, DD=day, hh=hours, aa=mtp number, bb=occultation number in current mtp DATA_SET_ID : ------------- VEX-Y/V-SPICAV-2-SOIR-V1.0 CONTENTS DESCRIPTION : ---------------------- Raw SOIR data records collected during the CRUISE and the different Venus orbit nominal phases 2. Archive Volume - Concept of Delivery --------------------------------------- Within the Planetary Science Archive (PSA) the archive volume represents an online delivery. This might be not fully compliant with the PDS standard 3.6, but the PSA itself can after the end of mission produce fully compatible archive volumes. Deliveries are based on the concept of a release and a revision. This concept allows the delivery of experiment data without the delivery of all supplementary information, that has already been delivered at the first initial delivery of a fully PDS compatible Archive Volume, containing the VOLDESC.CAT file and all necessary CATALOG, DOCUMENT, INDEX, DATA, etc directories and their content. Some PDS labels used in the SOIR Standard Data Archive are specifically related to the concept of release and revision. A data set release (or volume release) contains data from a well-defined period of time and is identified by the VOLUME_RELEASE_ID (4 digit number : [0001:9999]. A volume release is made of at least one revision : the initial revision. The initial revision contains the initial data of a data set release and is identified by a VOLUME_REVISION_ID equal to 0000. A following revision of the data set release (updated files, supplementary files, deleted files) would need the value of the VOLUME_REVISION_ID incremented by one. A release catalog object needs to be included in the catalog object to fully describe the release. The release object contains all keyword-value pairs that are necessary to identify a revision within a release. The DESCRIPTION part of the DATA_SET_RELEASE object will contain the full history of the release including all previous revisions. Each revision of a release is added in the release catalog object and all necessary information about this revision is given by a REVISION object. 3. File Formats ---------------- This section provides a brief description of the files and data objects available on the SOIR archive volume: text files, PDF files, HTML files, PNG files, and PDS objects.A complete description of each file format is available in the DOCUMENT/EAICD text on the archive volume. Text and detached PDS label files have fixed-length record format, and line lengths of 80 characters max, including a carriage return (ASCII 13) at the end of the record. This allows the files to be read by MS-DOS/ Windows,Unix, and VMS operating systems. Documents that contain formatting and figures that cannot be rendered as ASCII text are provided as HTML,JPEG, Microsoft Excel or PDF files. A PDS detached label provides descriptive information about the associated file. The PDS labels in the SOIR Standard Data Archive are conform to the PDS standards [Planetary Science Data Dictionary, 2001; PDS Standards Reference, 2003]. In general, the PDS label is an object-oriented structure consisting of sets of 'keyword = value' declarations; the object to which the label refers is denoted by a statement of the form: ^object = location in which the ^ character (also called a pointer in this context) indicates where to find the object. In a detached label, the location denotes the name of the file containing the object, along with the starting record or byte number, if there is more than one object in the file. For example: ^SOIR_TABLE = "20060807_M04_O02_105.TAB" indicates that the SOIR TABLE object can be found in the file 20060807_M04_O02_105.TAB, in the same directory as the detached label file. 4. File Naming Convention ------------------------- Data products provided by the SOIR team will have the following names: Science data tables and associated labels containing time, spectra, housekeeping and attitude data : ../VEXSPI_1003_1B/DATA/YYYYMMDD_Maa_Obb/YYYYMMDD_Maa_Obb_xxx.TAB ../VEXSPI_1003_1B/DATA/YYYYMMDD_Maa_Obb/YYYYMMDD_Maa_Obb_xxx.LBL Additional data table for telecommand (TC2 suffix) and its associated label : ../VEXSPI_1003_1B/DATA/YYYYMMDD_Maa_Obb/YYYYMMDD_Maa_Obb_TC1.TAB ../VEXSPI_1003_1B/DATA/YYYYMMDD_Maa_Obb/YYYYMMDD_Maa_Obb_TC1.LBL Additional data table for treatment (TRT_suffix) and its associated label : ../VEXSPI_1003_1B/DATA/YYYYMMDD_Maa_Obb/YYYYMMDD_Maa_Obb_TC2.TAB ../VEXSPI_1003_1B/DATA/YYYYMMDD_Maa_Obb/YYYYMMDD_Maa_Obb_TC2.LBL with YYYY=year, MM=month, DD=day, hh=hours, mm=minutes, ss=seconds, (a)aa=mtp number, bb=occultation number in current mtp, xxx=order number Example : Sept 12th 2006, MTP 05, Orbit 144, Occultation 13, 4 orders ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_126.TAB ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_126.LBL ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_127.TAB ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_127.LBL ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_128.TAB ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_128.LBL ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_129.TAB ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_129.LBL ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_TC1.TAB ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_TC1.LBL ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_TC2.TAB ../VEXSPI_1003_1B/DATA/20060912_M05_O13/20060912_M05_O13_TC2.LBL 4.
