    <description>This book catalogs the Apollo 15 photographic evaluation data. Section 2 explains
    and defines of all the photographic evaluation data elements (ephemeris data including state
    vectors and geometry). Sections 3 and 4 present data summaries for all the lightside sequences
    of the 3-inch metric (mapping) camera and the 24-inch panoramic camera photography. Each data
    summary includes a brief description of the trajectory reconstruction, telemetered data used,
    and the constants employed for the data processing. Each also contains a brief resume of the
    apparent data trends throughout the sequence and the ephemeris data for the first and last
    frames of the sequence (the item-page number is the frame number). This document is in the
    public domain.</description>
