Hi Yuan,<br><br>I believe yt has the functionality to compute the X-ray emission from a set of tables computed with Cloudy.  I believe Sam Skillman or Eric Hallman know how to do this, so maybe they can chime in.  It requires these data tables that do not ship with yt, but I think we would be happy to provide you with them.<br>

Dear all,<br>
<br>
I am trying to calculate the x-ray luminosity of my cool core cluster.<br>
I know that there is XRayEmissivity in yt but it is bremsstrahlung<br>
radiation only. I am trying to get the X-ray luminosity or emissivity<br>
from cooler gas as well.<br>
<br>
If anyone has a routine that can do this, please let me know. Thank you!<br>
<br>
Yuan<br>
