The BROWSE directory contains 3 subdirectories: level1, level2, and mosaics.
The contents of each subdirectory are discussed below.

LEVEL1:

This directory contains 2 subdirectories: "tiff" and "jpeg."

The "tiff" subdirectory contains 40 TIFF images, each with a standard PDS
document label. These images are browse versions of the level 1 polarized
(pol) and depolarized (dep) images found in the DATA\LEVEL1 directory. The
TIFFs are a log-scale stretch of -30 dB to +30 dB (0-255 DN) about the mean
of all the non-zero pixels in each 32-bit map.

The "jpeg" subdirectory contains 40 JPEG images, each with a standard PDS
document label. These images are browse versions of the TIFF images found in
the BROWSE\LEVEL1 directory.

LEVEL2:

This directory contains 2 subdirectories: "tiff" and "jpeg."

The "tiff" subdirectory contains 60 TIFF images, each with a standard PDS
document label. These images are browse versions of the level 2 polarized
(pol), depolarized (dep), and ratio (rat) images found in the DATA\LEVEL2
directory. The TIFFs are a log-scale stretch of -30 dB to +30 dB (0-255 DN)
about the mean of all the non-zero pixels in each 32-bit map.

The "jpeg" subdirectory contains 60 JPEG images, each with a standard PDS
document label. These images are browse versions of the TIFF images found in
the BROWSE\LEVEL2 directory.

MOSAICS:

This directory contains 2 JPEG documents, each with a standard PDS document
label. LUNAR_NEARSIDE_MOSAIC.JPG is a mosaic of the lunar nearside.
LUNAR_NEARSIDE_MOSAIC_LABELED.JPG is a mosaic of the lunar nearside with the
location of each "quad" mapped in this archive noted. These documents are
included as a guide for the dataset.

North is at the top of the frame in all of these images.
