Mode 1: Summary plot of MINPA ion and ENA observations in default mode.Position of Tianwen-1 orbiter in MSO (a) X-Y, (b) X-Z, and (c) X-√(Y² + Z²) planes. Ion count-rate spectrograms as functions of (d) energy, (e) polar angle, (f) mass, and azimuth angle. (h) Angle between X_MSO and MINPA polar axis (θ=0°, same with X_b). (i) Total count rate (black curve), H-ENA (red curve), He-ENA (green curve), and O-ENA (blue curve) count rates summed along energy and azimuth angle. Count-rate spectrograms as functions of energy for (j) H-ENA, (k) He-ENA and (l) O-ENA. (m) Count-rate spectrogram as function of azimuth angle for H-ENA. The vertical blue and red dashed lines in (d-m) display the times of bow-shock and MPB crossiings based on the empirical model from Trotignon et al. [PSS, 2006], the vertical black dashed line shows the crossing of Mars optical shadow. In (f), the three dashed lines from bottom denote Mass=1, 16, and 44, respectively. In (g) and (m), the thin blue dashed curve shows the β_Sun from 2B datafile, and the thick black dashed curve is the homebrewed β_Sun.
