I have been working through using the software and have come across a strange bug/thing happening.
During the reduction of some Rb-Sr data I have had exported a few samples with negative Rb/Sr ratios, the issue is being is that my counts for Sr86, Sr87 and Rb87 are all positive in both inputs and intermediate, but it is when I get to the final output stage that the ratio inverts and turns negative.
The sample I am having the issue with is a muscovite sample so the Sr/Sr would already be low, but there is no reason as to why the output ratio just inverts and turns negative. I am using NIST610 as my reference.
I don't really know what to do, what information can I give you to help me/do you know how to fix this issue?
I have other negative ratios throughout my samples but they are randomly spread out throughout the sample's points and not consistently negative like this sample I have.
