  We present the stellar main sequence luminosity function (LF) of the
disrupted, low-mass, low-concentration globular cluster Palomar 5 and its
well-defined tidal tails, which emanate from the cluster as a result of its
tidal interaction with the Milky Way. The results of our deep (B ~ 24.5)
wide-field photometry unequivocally indicate that preferentially fainter stars
were removed from the cluster so that the LF of the cluster's main body
exhibits a significant degree of flattening compared to other globular
clusters. There is clear evidence of mass segregation, which is reflected in a
radial variation of the LFs. The LF of the tidal tails is distinctly enhanced
with faint, low-mass stars. Pal 5 exhibits a binary main sequence, and we
estimate a photometric binary frequency of roughly 10%. Also the binaries show
evidence of mass segregation with more massive binary systems being more
strongly concentrated toward the cluster center.
