Introduction The Bloomsburg University Goniometer(BUG) was used to make bidirectional reflectance distribution function (BRDF) measurements of Mars soil analogs at Mars Exploration Rover (MER) Panoramic Camera (Pancam) wavelengths. This archive contains the results of those measurements. 2. File Formats This archive consists of 60 tabular data files, each with an accompanying detached PDS label. The data are organized within 5 folders, corresponding to the 5 soil samples analyzed. Within each of the 5 folders are tabular data files containing the BRDF results for each of the MER Pancam wavelengths. Also in each of the 5 folders is a file containing the reflectance spectrum for the particular soil sample. Please see BUGMARS_DS.CAT for detailed information describing the data. All detached label and document files are stream format files, with a carriage return (ASCII 13) and a line feed character (ASCII 10) at the end of each record. This allows the files to be read by the MacOS, Windows, and Unix operating systems. All tabular files are described by detached PDS labels, which are label files having the same name as the data files they describe, with the extension .LBL. For example, the file INDEX.TAB is accompanied by the detached label file INDEX.LBL in the same directory. Tabular files are formatted so that they may be read directly into many database management systems (DBMS) or spreadsheet programs on various computers. All fields are separated by commas, and character fields are enclosed in double quotation marks ("). The "start byte" and "bytes" values listed in a PDS label do not include the commas between fields or the quotation marks surrounding character fields. The records are of fixed length, and the last two bytes of each record contain the ASCII carriage return and line feed characters. This allows a table to be treated as a fixed length record file on computers that support this file type and as a normal text file on other computers. 3. Archive Contents Files in this archive are organized into a series of subdirectories below the top-level directory. The archive organization and the contents of each directory are described below. Top-level Directory ------------------- AAREADME.TXT The file you are currently reading. VOLDESC.CAT This text file contains a description of the volume contents as a PDS catalog object. It is a required file on PDS archive volumes. CATALOG Directory ----------------- Files in the CATALOG directory are text files containing documentation formatted in PDS object description language. The files contain information about the B.U.G instrument and laboratory, the data set, references, and personnel involved in archiving the data. See the file CATINFO.TXT for details. DATA Directory -------------- The data files and associated PDS labels are stored in the DATA directory. INDEX Directory --------------- The INDEX directory contains a PDS index file for this archive. An index file is an ASCII table with each record (or line) in the table containing information about a single data product in archive. See the file INDXINFO.TXT for additional details. EXTRAS Directory ---------------- The EXTRAS directory contains ancillary material that may be useful but is not required for the inderstanding of the archive. See EXTRINFO.TXT for additional details. GEOMETRY Directory ------------------ The GEOMETRY Directory contains files needed to describe the observation geometry for the data in the archive. 4.
