recombH

procedure recombH[, dn]

Plot the Hydrogen recombination lines for quantum jump of dN. Defaults to plotting the alpha lines (dN=1).

Originally by Glen Langston, glangsto\@nrao.edu

Molecular Formula from Tools of RadioAstronomy, Rolfs and Wilson, 2000, pg 334

 v_ki = Z^2 R_M ( 1/i^2  - 1/k^2), where R_M = R_infinity/(1 + m/M)
 v_ki = R_A     ( 1/i^2  - 1/k^2) (k > i)
 
 where for hydrogen values (MHz), R_a = 3.28805129E9
