CCD (left) and HID (right) of the persistent emission of the 2024 outburst observed by NICER. Different colors correspond to different observations, and each point represents a 32-second data segment. Soft color is defined as the ratio of the count rates in the 1.8−3.5 keV band to those in the 0.5−1.8 keV band, while hard color is defined as the ratio of the count rates in the 5.2−6.8 keV band to those in the 3.5−5.2 keV band. The energy band selections for the CCD and HID are consistent with those in Ng et al. (2024).
