Caption: Figure 2.

RadioAstron (Space Radio Telescope–GBT) 22 GHz interferometer response from observations of the quasar 3C 273 on 2013 February 2 with a projected baseline of 7.6 Gλ. The ratio of interferometer fringe amplitude to the average noise amplitude is shown as a function of the residual delay (in nanoseconds) and fringe rate (in millihertz).
