O II 4651 Å recombination line is very faint in Cloudy models #19

Closed will-henney closed 12 years ago

It comes out with some ridiculous strength, such as 1e-20 times H beta. There must be something wrong.

will-henney commented 12 years ago

One thing I don't understand is that there are two different labels: O 2 and O 2r. The first is used in PntForLin while the second is used for lindst. See penultimate comment to issue #26. What is the difference?

It turns out that O 2r is what we needed. Using the following input script:

test
print line faint -30
save last lines, emissivity "cloudy-line-test.em"
H  1  4861A   // H beta
O 2r  4651A   // O II 
O  2  4651A   // is this also O II?
end of lines

we get the following emissivity output:

#depth  H  1  4861A O 2R  4651A O  2  4651A
5.00000e-01 -16.8771    -19.8005    -35.9298
1.50000e+00 -16.8771    -19.8005    -35.9298

Notice that the O 2R column is sensible, but the O 2 one isn't.
