Previous resolution limited measurements indicated that {\\Delta}f may be below 1 GHz - much smaller than expected from a purely cavity-induced synchronization. While at low bias we found {\\Delta}f to be not smaller than ? 500 MHz, at high bias, where a hotspot coexists with regions which are still superconducting, {\\Delta}f turned out to be as narrow as 23 MHz.
