Line Intensity ratios of Fe24 255.10A and Fe23 263.76A

[Deepak Kathait]

Hi,

I am trying to calculate temperatures for an EIS observation using the ratio of the above-mentioned lines. How do I calculate the ratio of the these lines from chiantipy.

Thanks in advance

Deepak

Just for clarity, I would like to calculate the intensity ratio vs temperature values/plot for the above-mentioned lines so I can diagnose the temperature in my EIS observation

Deepak,

the obvious thing to do is to calculate the contribution function 

G(T) for the two lines, then you take the ratio and get the 

isothermal temperature. Or if you have more lines you can plot the 

EM loci curves, i.e. plot I/G(T) for the lines, the crossing will give 

you the ionisation temperature (cf. Del Zanna & Mason living review)

To use ChiantiPy, go to the Quick Start guide on readthedocs and go to the ' muli-ion class bunch'

there is a demo there on how to calculate the intensity ratio of lines from 2 different ions as a function of temperature

hope this help

Hi Giulio, 

I really appreciate your help.

Thank You

Hi Ken,

Thank you for your valuable input. It seems I missed this while going through the documentation.
