Distributions of small-scale flux ropes via Ulysses measurements under two algorithm scenarios (with and without thermal pressure). (a) Duration with 25 minutes as bin size. (b) Scale size with 0.0025 au as bin size. (c) The average plasma β with 0.1 as bin size. (d) The wall-to-wall time with 10 minutes as bin size. The blue dots represent searching results with thermal pressure while the dark orange dots represent results without it.
