I’ve just discovered that I entered the wrong dwell times for a dataset I spent some time processing (dwell times for all isotopes are too short by a factor of 5). I am using Iolite (version 3.65, with Igor Pro 7.08 on a Windows computer) to process U–Pb geochronology data with the VizualageUcomPbine DRS. My input data are FIN2 files with data in CPS.
I corrected the dwell times and re-crunched the data, but there seemed to be no change in the results on channels such as 207Pb_CPS (which I thought was a good candidate to be affected by the dwell times), so I wasn’t sure if it had really updated the dwell times.
It’s not clear to me what the dwell times are actually being used for, and whether it in fact matters that I got them so drastically wrong. Can anyone tell me if this error will have made a difference to the results I get? And if so, is there any way to correct the dwell times in the existing file and recrunch, to avoid starting the whole lengthy process again from the import step?
Any insight would be much appreciated!
