Query: Optimal Stereoscopic Angle for Reconstructing Solar Wind Inhomogeneous
  Structures   This paper is aimed at finding the best separation angle between spacecraft
for the three-dimensional reconstruction of solar-wind inhomogeneous structures
by the CORrelation-Aided Reconstruction(CORAR) method. The analysis is based on
the dual-point heliospheric observations from the STEREO HI-1 cameras. We
produced synthetic HI-1 white-light images containing artificial blob-like
structures in different positions in the common field of view of the two HI-1
cameras and reconstruct the structures with CORAR method. The distributions of
performance levels of the reconstruction for spacecraft separation of
$60^{\circ}$, $90^{\circ}$, $120^{\circ}$ and $150^{\circ}$ are obtained. It is
found that when the separation angle is $120^{\circ}$, the performance of the
reconstruction is the best and the separation angle of $90^{\circ}$ is the
next. A brief discussion of the results are given as well. Based on this study,
we suggest the optimal layout scheme of the recently proposed Solar Ring
mission, which is designed to routinely observe the Sun and the inner
heliosphere from multiple perspectives in the ecliptic plane.
