Residual fringe delay (top) and delay rate (bottom) solutions at 5 GHz, obtained for the SRT from the data recorded at the tracking stations in Green Bank (light gray, UT 04–12, 10 January and UT 01–08, 11 January) and Puschino (dark gray, UT 16–24, 10 January). The squares and triangles denote the solutions for the first and second IF band, respectively. The time variations of the residual delays and the delay rates likely reflect the effect of the accelerated motion of the SRT, which was not accounted for during the fringe fitting.
