Radio versus X-ray luminosities of LMXBs in the hard state (adapted from Bahramian & Rushton 2022), with EP J175257.3–351923 overlaid. The radio constraint is a 3σ VLASS upper limit at 3 GHz (2026 February 1), converted to 5 GHz assuming a flat radio spectrum. The X-ray luminosity is from the EP/FXT observation on 2026 April 22. Although the X-ray and radio observations are not simultaneous, the source had entered a plateau phase, and the X-ray luminosity is therefore assumed to be comparable at the VLASS epoch. Both luminosities assume a distance of 8 kpc.
