Hi all,
I have just released a v4 version of a Sm-Nd DRS with downhole frationation correction. This DRS was based on the v3 DRS distributed by Chris Fisher and written by Chad Paton.
I got the DH, beamsecond and appropriate Widget from examples in GitHub and modified it with the help of Joe Petrus.
You can find it in the DRS folder on: https://github.com/iolite-LA-ICP-MS/iolite4-python-examples
Or from my own repository at: https://github.com/VitorBarrote/iolite4_scripts_DRS
This DRS can be referenced directly from the GitHub repository as DOI: 10.5281/zenodo.5512126, the original v3 DRS is from Fisher et al. (2017) doi:https://doi.org/10.1002/2017GC007187.
We have tested out in previous datasets and got consistent results, however, we recommend that it be cross-validated by the community. Before using it make sure that you check the code because the masses used may need to be adjusted for your instrument. If you need help with that I'm happy to provide.
We'd like this to be as colab as possible, so please feel free to contribute to the DRS.
As of right now the DH is much simpler than the one of the in-build U-Pb DRSs that come with Iolite, so a few areas where this DRS can be improve include:
- DH curve fitting options
-display all RM in the DH fit, not just the avg.
Please feel free to provide feedback here in this thread if you have any suggestions, comments or questions about the new DRS.
Cheers 😀
