  • Found cause of position stretch in simulations - did not account for relative distance change in relation to declination angle. Only applies to right ascension.
  • Correction:
 \begin{equation} \Delta \alpha _{corrected}=\Delta \alpha \cos{\delta } \end{equation}  $\Delta \alpha _{corrected}$: Relative distance separation on focal sphere at declination $\delta$  \\ $\Delta \alpha$: Relative distance separation for $\delta = 0$.
