Hi, I am producing with Cloudy 07.02.01 some fits tables to be used as XSPEC models. The spectrum to be fitted is dominated by absorption lines produced in an...
the agn command, in effect, combines a blackbody and a powerlaw. you could set the blackbody part with the blackbody command, then add a variable power-law...
Hi Valentina this is now fixed on the trunk. most of the punch hydrogen options had similar problems so the fix is not just a few lines of code. This will go...
Apologies in advance if this was in the docs that I could not find. I would like the local spectrum as a function of depth in the cloud; it appears that punch...
which part of the radiation field? The local source function? The attenuated incident continuum? diffuse emission? these are all stored, and transferred,...
Hi, The are limitations imposed by the way Cloudy treats radiative transfer, more in particular the fact that reflected light is treated using escape...
... The PUNCH LINE LIST command will do what you want. You create a file with a list of the emission lines you want then enter the name of the file as an...
Ryan, have you had a chance to check into any possible changes in the atable files introduced in c07.02.01, as referenced below in a previous post? ---...
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...
