Probability of detecting a X-ray/radio event given a certain X-ray/radio efficiency η observing in the radio band with the SRT-P (left) or the uGMRT Band 3 (right). Supposing that the event is above the fluence X-ray threshold (left y-axis) the colormap shows the probability of detecting a radio burst with radio fluence (right y-axis), constrained by the efficiency η, as a function of the simultaneous exposure (x-axis). The dashed lines represent the iso-probability contour plots for a probability of 50, 90, and 99.9 %.
