  The Trans-Neptunian Objects (TNOs) may preserve evidence of planet building
in their orbital and size-distributions. While all populations show steep
size-distributions for large objects, recently relative deficit of Neptunian
Trojans and scattering objects with diameters $D<100\,\mathrm{km}$ were
detected. We have investigated this deficit with a 32 square degree survey,
detecting 77 TNOs to a limiting $r$-band magnitude of 24.6. Our Plutinos sample
(18 objects in 3:2 mean motion resonance with Neptune) also shows a deficit of
$D<100\,\mathrm{km}$ objects. We reject a single power-law size-distribution
and find that the Plutinos favour a divot. The Plutinos are thus added the list
of populations with a deficit of $D<100\,\mathrm{km}$ objects. The fact that
three independent samples of three different populations show this trend
suggests that it is a real feature, possibly shared by all hot TNO populations
as a remnant of "born big" planetesimal formation processes. We surmise the
existence of $9000\pm3000$ Plutinos with $H_r\leq8.66$ and
$37000^{+12000}_{-10000}$ Plutinos with $H_r\leq10.0$. Our survey also
discovered one temporary Uranian Trojan, one temporary Neptunian Trojans and
one stable Neptunian Trojan, from which we derive populations of
$110^{+500}_{-100}$, $210^{+900}_{-200}$ and $150^{+600}_{-140}$ ,
respectively, with $H_r\leq10.0$. The Neptunian Trojans are thus less numerous
than the main belt asteroids, which has over 700 asteroids with $H_r\leq10.0$.
With such numbers, the temporary Neptunian Trojans cannot be previously stable
Trojans that happen to be escaping the resonance now; they must be captured
from another reservoir. With three 3:1 and one 4:1 resonators, we add to the
growing evidence that the high-order resonances are more populated than
expected.
