  \caption{The number of background stars {\em expected} in our ADONIS and NACO fields of view, based on the background star study of \cite{shatsky2002}. Column~1 lists the four regions for which we study the background statistics. The targets with Galactic latitude $|b|\leq 5^\circ$ are included in the region GP. The other targets are grouped according to their membership of US, UCL, and LCC. For the 177~targets {\em only} observed with ADONIS and the 22~targets observed with NACO we list the expected number of background stars per field of view, and the number of targets observed in the four regions. In total we expect to find $70.75 \pm 4.90$ background stars in the ADONIS sample, and $18.96 \pm 3.96$ in the NACO sample.  \label{table: backgroundstars}}
