Introduction The Bloomsburg University Goniometer (BUG) was used to make bidirectional reflectance distribution function (BRDF) measurements of Apollo samples at several wavelengths. The laboratory is described in "Shepard, M.K., The Bloomsburg University Goniometer (B.U.G.) Laboratory: An Integrated Laboratory for Measuring Bidirectional Reflectance Functions, Lunar and Planetary Science Conference XXXII, Abstract 1015, 2001". This abstract can be accessed at: http://www.lpi.usra.edu/meetings/lpsc2001/pdf/1015.pdf. This archive contains the results of those measurements. 2. File Formats This archive consists of tabular data files, each with an accompanying detached PDS label. Please see BUGAPOLLO_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 data (*.CSV) 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. Data files are formatted so that they may be read directly into many text editors or spreadsheet programs. All fields are separated by commas. The last two bytes of each record contain the ASCII carriage return and line feed characters. All tabular (*.TAB) files are described by detached PDS labels, which are label files having the same name as the 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. BROWSE Directory ---------------- The BROWSE Directory contains a set of TIFF and JPEG images that show sample plots of the data from the DATA Directory. CATALOG Directory ----------------- Files in the CATALOG directory are text files containing documentation formatted in PDS object description language. The files contain information about the BUG 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. GEOMETRY Directory ------------------ The GEOMETRY directory contains files needed to describe the observation geometry for the data in the archive. 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. 4.
