X‐ray color‐color diagram of 4U 1702−429. Each point represents a 256 s average over the 16 s ratios, excluding bursts, when all five detectors were on. Intervals in which kilohertz QPOs were observed are represented by open circles. The filled circles represent intervals in which no kilohertz QPO is detected. The "hard color" is the ratio of counts in the 9.43–16.0 and 6.52–9.43 keV bands and the "soft color" is the ratio in the 3.63–6.52 and 1.86–3.63 keV bands.
