recombc

procedure recombc[, dn], [/doPrint]

Plot the Carbon 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 carbon values (MHz), R_a = 3.28969163E9

Parameters




dn


in, optional

integer (def. 1)



 The quantum jump
 to calculate (1 is alpha, 2 is beta, etc).






Keywords




doPrint


in, optional

boolean (def. 0)



 optionally print
 the line frequencies.  The printed frequencies are the line
 frequencies in the frame being displayed on the plotter.
