Note: For C and m parameter determination, the tool currently uses simplified placeholders. Provide multiple datasets in the text area, separated by a line containing '---NEW_DATASET---' for future, more advanced versions.

Varying Strain Rates (s⁻¹, comma-separated, for C calculation - e.g., 1, 10, 100):

Varying Temperatures (K, comma-separated, for m calculation - e.g., 298, 573, 773):
