I forgot to respond earlier. Sorry about that. There are really two questions here. One is whether the atables should include line absorption, and the other...
I have a question about how Cloudy generates XSPEC mtables when a grid is run. Although the atables are (I expect) fairly comparable to the equivalent "punch...
There was a problem with the mtables only including the absorption of the last slab. This was fixed in late June and is included in 07.02.01 (which was...
I'm using v07.02.01, but I checked the file just to be sure. The line of code is correct. Just wondering, do you calculate the mtable values by dividing the ...
I'm having trouble understanding the ionization of Ar in calculations I've done with Cloudy. I use "punch ionization rates argon", which gives me the total...
... there is not any one answer - it depends on the simulation. My first hunch would be HeII Lya - all the lines are included as ionization sources. To...
... Gary, Thanks for your response. Here's the problem. When I output the photoionization rates, e.g. using "punch gammas element argon 2" I get a rate of...
... It turns out I was right! The rate is due to charge transfer: Ar+ + He+ -> Ar+2 + He0 That rate, from Dalgarno & Butler (1980) is very high, 1.1E-10. The...
... did you try the "print arrays" command? that dumps out vast amounts of information about individual processes. you are right that this information should...
No, the mtable values are not calculated in that way. Both the transmitted continuum and the mtable values are accumulated results and are, of course, ...
We would like some help understanding differences between Cloudy and results obtained using simpler calculations using published rates. We are using cloudy to...
Although the output values for the two are comparable, I suspected as much. More to the original point (and original posts), our interest is to gain more...
Thanks for the guidance, Ryan. We'll take a look with this new information in hand - BKA ... depth from ... lines. Both ... and high ... energy ... ...
Hi, Just three short questions: Does Cloudy use full Klein-Nishina cross section? Is there any option that turn this on? Would Compton heating from a spectral...
... it is always included. The compton exchange limit is exact, as is shown in hazy and several test cases. The mathews & ferland 1987 and Ferland & Rees...
Hi everybody !!! I have found an unidentified emission line in a Seyfert 2 spectra at 9625 angstroms. I've tried to reproduce it with cloudy, but I don't find...
That would be hard to answer like that - ie. it depends on relative line ratios, other lines present etc. But you will probably find the Atomic Line list a...
Thank you Jarle, but I used this Atomic Line list, and I have many candidates, as [Fe II], [P II] or He I. I tried to reproduce the spectrum then with cloudy...
... Cloudy may not be want you want to use if you are trying to identify an unknown line. The better approach would be to understand the line in the context...
You could perhaps compare the intensity of your unknown line to HeI 4471. If the ratio is close to 5d-3, it is an HeI line. You can cross check by looking for...
Note that if the line is indeed the HeI line, it is from an upper level that is not included by default in Cloudy's helium model. You will need to increase...
I'm doing a high-resolution Cloudy run (with "set continuum resolution 0.1") and I'm getting the following message on my output: NOTE OpacityCreate1Element...
Thanks Peter. I thought so. Actually, I've seen a subsequent and perhaps related problem that actually caused a thrown assert and crashed Cloudy. With the...
We were aware of this problem (although it looks like we neglected to document it anywhere). This will be fixed in the next major upgrade, with an expected...
Hi, We have been looking for the references of the transition probabilities used by Cloudy (c07.02.01) for different ions in the files "cool_*.cpp" and cannot...
