Smoke plume visualization for various configurations of glass capillary (low-contrast landmark) and spherical bead (high-contrast landmark) objects. These tests ascertain the laminarity of the flow for the different conditions, and also help determine the average width of the odor plume when the airflow in the wind tunnel is set at 0.1 m/s (see Fig. 1B,C and Fig. S1). Diameter of the bead is 6 mm and glass capillary is 1 mm. Smoke was generated using incense
