Simultaneous X-ray and radio light curves for the 2020, 2022A, and 2022B epochs: the top panel reports the 0.2 − 2 keV light curve, and the lower panel the radio light curve at 6 GHz as measured by the VLA. In the lower panel, RX J1301.9+2747 is shown in green, and a different radio source in the field is shown in gray to serve as a check source. Each portion of the broken axes represents 0.25 d. Note that the flux density of the check source has been scaled down by a factor of 15. The gray shaded region shows the mean value for the 2020 observation plus or minus 5%, the absolute accuracy of the VLA flux density calibration.
