VLTI configuration for measurements of Achernar
The configuration of the VLT Interferometer (VLTI) for the measurements of Achernar, a rapidly rotating star. The moveable, 40-cm test telescopes were positioned at specific "stations" (E0 + G1; B3 + M0; with baselines of 66 m and 140 m, respectively), allowing contiguous measurements in two nearly perpendicular directions. The two light beams were then sent via the path-compensating VLTI Delay Lines to the VINCI test instrument where they combined to form interferometric fringes. The positions of the four 8.2-m VLT Unit Telescopes are indicated by numbered circles.
