This directory contains files associated with extra functionality beyond
PDS archiving requirements which we hope will be useful but are not
subject to PDS standards.

The primary available feature is a Graphical Data Browser Index
implemented as an HTML file, BROWSE.HTM, along with associated HTML
imagemap and JavaScript source files.  Taking advantage of the user's
native web browser, this feature presents a list of time intervals
included on individual "contact sheets" containing miniature versions of
frequency-time spectrograms of all the data contained in this volume.
These contact sheets are useful for browsing long time periods to search
for large-scale features or to determine if data are available during a
specific time of interest.  Using a sufficiently enabled web browser, the
user can click on one of the small spectrograms to obtain a
full-resolution spectrogram with options to view the associated label
file, save the binary waveform file, or launch an interactive analysis
application.
