a–c, [H, K, 0.5] plane diffraction maps at 440 K, 140 K and 70 K, respectively. At 440 K (T > TN), no magnetic peak is observed; at 140 K (TCDW < T < TN), AFM peaks emerge at H, K = 1, 2, 3…. At 70 K (T < TCDW), further CDW peaks emerge at H, K = 0.5, 1.5, 2.5…. d–f, [H, K, 4] plane diffraction maps at 440 K, 140 K and 70 K, respectively. Colour bar is in log scale. At 440 K (T > TN) and 140 K (TCDW < T < TN), structural peaks are present at H, K = 1, 2, 3…; at 70 K (T < TCDW), CDW peaks emerge at H, K = 0.5, 1.5, 2.5….
