The preliminary identification has been thoroughly checked using the RionID software. We have confirmed that the identification is accurate.

Attached can be found the simulation file with each of the expected ions, their revolutions frequencies in the 125th harmonic and expected yield from the LISE file attached.
Also attached are some figures from RionID that highlight the region of interest for the 124th and 125th harmonics. The center frequency of the 245 MHz resonator is closer to the 124th harmonic for 229Th+89 which is located at 244.769 MHz. 

If necessary, we can slightly shift the resonator curve to higher frequencies to fine-tune the signal-to-noise ratio for 229Th+89.
