Extended Data Fig. 2: The observed azimuthally averaged radial profile of the stellar disc of R Doradus.
From: One month convection timescale on the surface of a giant evolved star
The radial profile, in the top panel, is generated from a combination of the three last epochs. The dashed line indicates the uniform disc model that minimizes the residual flux shown in the bottom panel. The error bars on the radial profile are close to the line width, with a largest error of 5 × 10−5 Jy beam−1. The error bars on the residual fraction are indicated with the vertical line segments.
