CODATA Consistency #40

Closed eadkins333 closed 3 years ago

eadkins333 commented 3 years ago

The line intensity calculations use the Boltzmann and Avogadro constants. The values currently used in HITRAN are not the same as the CODATA values for these two constants, both were recently redefined by the CIPM. Thus, for the sake of maintaining consistency with the SI, we should use the CODATA values.

This involves coding in the line intensity calculation into MATS.

c2≡hc/k. This also should be redefined as the value based on CODATA values for h, c, and k

Hardwired in the h, c, k, and Na constants using CODATA values with links to the CODATA site for each (include date of retrieval for reference). Calculate c2 from these. Remove the hapi environmental line intensity call and include line intensity dependence directly in the MATS code. Rework Doppler broadening calculation to use Na instead of cmassMol (like the inverse of Na)
