Swift-XRT observations for PKS 1725+123. Light curves of F0.3−10 (black points in the first panels), F0.3−2 (red points in the second panels), F2−10 (blue points in the second panels), Γγ (green points in the third panels), and the HR (orange points in the fourth panels) are respectively depicted. The gray shaded area indicates the quasi-simultaneous observations (on August 19 and 21) corresponding to the TeV detections. The left panels show the three historical Swift-XRT observations, while the right panels display the Swift-XRT follow-up observations of the TeV detection for the source. MJD 60755 corresponds to 2025 March 21.
