Missing O II permitted lines in Cloudy #26

Closed nahieflores closed 12 years ago

nahieflores commented 12 years ago

List of O II lines observed in proplyds that seem to be missing from Cloudy.

4638 4641 4661 and 4676 Å - missing in standard Cloudy and Chianti
- Standard Cloudy has lots of optical O II lines in the 4000-5000 Å range, but not these ones
- Presumably Cloudy's O 2r 4651A is some combination of the 4649 and 4650 lines
- Chianti's o/o_2/o_2.wgfa file has some of the forbidden lines (the 3728 doublet, the 2471 doublet and the 7322 doublet) but none of the optical recombination lines
Note potential confusion with lines that are in Cloudy
- [N III] 4641 Å
- [C III] 4649 Å

I have edited this issue to merge in related issue #27, which I will close

Originally we had the [Cl III] 5539 Å line listed here. However, this is in Cloudy, but with the wavelength 5538 Å.

More edits to clarify things. Nahiely had originally mentioned 4649 4650, but these are surely the same as Cloudy's O 2r 4651A

Actually Cloudy does have these lines!

From prt_lines_lv1_li_ne.cpp:893...

    /* recombination and specific pump for OII 4638.86-4696.35 (8 lines) */
    rec = GetLineRec(82, 4651 );
    PntForLine(4651.,"O  2",&ipnt);
    lindst(rec,4651,"O 2r",ipnt,'r',true,
        " O II 4651 total recombination, 4638.86-4696.35 (8 lines)  " );

But they are all lumped together with the 4651 tag.

So I am closing the issue. Maybe it would be useful to split out the separate components, but that should be a new issue, and it may not even be necessary.
