The Impact of Spectroscopic Fibre Collisions on the Observed Angular
  Correlation Function
  The design of some spectroscopic galaxy surveys is such that fibre collisions
can affect the completeness of the survey. To quantify this effect, we compare
the two-point correlation functions, $\omega(\theta)$, of two surveys with
differing observational strategies. Fibre collisions are an accepted
consequence of the design of the Sloan Digital Sky Survey's spectroscopic
campaign (SDSS), whereas the Galaxy And Mass Assembly survey (GAMA) circumvents
fibre-collisions by re-observing fields using different fibre configurations.
We show that the correlation functions of these surveys diverge at scales
smaller than the SDSS fibre collision limit, and that at separations smaller
than $20''$ $\omega(\theta)_{\text{GAMA}} > \omega(\theta)_{\text{SDSS}}$ with
$>4\sigma$ confidence.
