[chhh]

Allow setting multiple custom isolation windows and corresponding injection times for the quadrupole.

This is in the works.

If I understand correctly, this was enabled as of Tune version 3.5. See Changelog; for each window you can supply a target like so:

scan.Values["PrecursorMass"] = "195,524,1522";
scan.Values["IsolationWidth"] = "5,5,5";
scan.Values["MSXTargets"] = "1000,10000,100000";
