    246246fixapex2_0410b: The total experiment time was 30 minutes. ADV measurements were collected from 15 to 35 minutes after the start of the experiment at the second apex (Position X4).

     250The tank was rotated with a rate of 0.083 rad/s (0.8 rpm), which corresponds to a Rossby number of +1. Two experiments were conducted.

     252Experiment name: rotstr1_0510a and rotapex2_0510b. File Names: rotstr1_0510a, rotapex2_0510b. Inflow rate for both experiments: Started with 13.1 L/s and then was decreased to 5.84 L/s until it reached a constant level.

     254rotstr1_0510a: The total experiment time was 36 mins. PIV measurements were conducted for the first 10 minutes of the experiment. However, the water was not as clear as expected and there were a lot of bubbles on the tank’s wall, so the quality of the PIV data may be low. Density excess and temperature were 20 kg/m^3^ and 22.6°C, respectively. ADV data was collected at the straight section (Position X1 - 75% down straight section, 58 cm upstream from the end of the straight section) from 15 to 25 min after the flow rate became constant. 7 sets of siphon samples were collected at 5, 10, 15, 20, 25, 30, and 35 minutes after the start of the experiment, with a duration of 1 minute. Cross stream UVP collected data from 5 to 15 minutes and down-stream UVP collected data from 25 to 35 minutes.

     256rotapex2_0510b: The total experiment was 30 minutes. Temperature and density excess were 23°C and 18.8 kg/m^3^, respectively. ADV measurements were collected from 15 to 35 minutes after the start of the experiment at the second apex (Position X4).
