"Visibility Curve" of the star Psi Phoenicis

This chart shows the "visibility curve" for the red giant star Psi Phoenicis as measured on two nights (16 data sets; three points to the right) with two VLT UTs (ANTU + MELIPAL) for three different positions in the sky and on four nights with the 40-cm test siderostats on a shorter 16-m baseline (8 data sets; one point to the left); see the text below. From the fitted curve, a preliminary value of the angular diameter is 8.21 ± 0.02 milli-arcsec (mas).
