Proximate and ultimate analysis
Use the Proximate class to express proximate analysis values as different bases. Bases are as-determined (ad), as-received (ar), dry (d), and dry ash-free (daf).
>>> prox = cm.Proximate([47.26, 40.05, 4.46, 8.23], 'ad')
>>> print(prox)

Use the Ultimate class to express ultimate analysis values as different bases. Bases are as-determined (ad), as-received (ar), dry (d), and dry ash-free (daf).
