You'll see 5 time-series light curves, each generated from a power-law PSD of different noise color:
Your mission: guess the PSD slope α from the shape of the light curve alone.
α ≈ 0 — white noise: jittery, no coherent structure, zero correlation timescale
α ≈ 1 — pink / flicker noise: structure at many scales
α ≈ 2 — red / Brownian noise: smooth wandering with little jitter
α ≈ 3 — very red noise: slowest, smoothest drifts, longest correlation timescales
Each round earns 0–100 points (linear scoring: exact match = 100, off by 0.5+ = 0).
Total possible score: 500.
