| + | |||
| + | The (non-Cl-36) exposure age calculator can also be used in reverse mode for production rate calibration by setting the mlmfile field to ' | ||
| + | |||
| + | This requires different input that includes the independent age information. Suitable calibration data in the correct input format can be obtained | ||
| + | |||
| + | Note: you can only calibrate the production rate for one nuclide at a time. So the input data can only have measurements of one nuclide; otherwise generates an error. | ||
| + | |||
| + | Here is an example in MATLAB that (i) scrapes calibration data in the appropriate input form from the ICE-D: | ||
| + | |||
| + | This is somewhat complicated but if you are familiar with how the exposure age calculators work, and have gotten through all the previous examples, | ||
| + | |||
