This is a preliminary result during 4:00-19:00 April 1st 2025. 
I correct the frequency drift of 194Pb82+ ions injection by injection.

I have analyzed all injection data during 4:00-19:00 and calculated the frequency of 194Pb82+ for each injection. This is the frequency of 194Pb82+ as 
a function of time. You can clearly see that the frequency of 194Pb82+ was drifted from 408.603 to 408.600 MHz. The variation of frequency is about 
3kHz.
