auto tagging of analyses with saturated amplifier #1909

Jake:

Would it be possible for Pychron to automatically mark and reject analyses where a beam exceeds the saturation value of an amplifier? These are almost always cases where 40Ar is > 50xx counts. These analyses are always compromised, but currently need to be weeded out one at a time by the user. Saturated analyses do not always stand out from good data on the basis of anomalous ages, but the ages are always inaccurate. They could be automatically tagged as "invalid-saturated" and eliminated immediately from data sets, thereby saving a little future heartache.

Thanks, Bill

use a series to plot 40Ar intensity. select analyses >5000, tag as invalid
