We are using Chemstation Data Analysis E.02.02.1431. Today while trying to manually integrate a Q2 ion in Qedit for a SIM method, I noticed the peak height for the target ion slightly changed even though I only touched the Q2 ion. I re-created this phenomenon by changing the integration for Q1, and the target ion again changed slightly to the same new height value.

Does anyone know why this sometimes (not always) happens and how to avoid it? Is the target height changing because the integration has changed itself or is the number just arbitrarily changing? We use the RTE Integrator. Thanks!
