A XSPEC Composite Model Partial Flux Calculations

AI Thread Summary
The discussion revolves around performing partial flux calculations using XSPEC with a model that includes a Gaussian component. The user, Joe, has successfully calculated the Gaussian flux contribution, which is 8.31189E-11 erg/s/cm^2, and the total flux of the model as 0.069691 photons (8.5637e-10 ergs/cm^2/s). Joe seeks guidance on converting the Gaussian flux value to counts per second per keV. The thread highlights the need for assistance in this specific conversion process. The conversation emphasizes the technical aspects of XSPEC modeling and flux calculations.

TL;DR Summary
XSPEC
Hello,
I am running a model in XSPEC: phabs*(pow + cflux*gaussian) on a WSL Ubuntu terminal.
The fit output shows lg10flux = -10.0803 which converts to a flux of 8.31189E-11 erg/s/cm^2. This is correct for the gaussian flux contribution.
The flux command produces:
0.069691 photons (8.5637e-10 ergs/cm^2/s)
This is correct for the entire model.
What I'd like to do is convert the gaussian flux of 8.31189E-11 erg/s/cm^2 to counts/s/keV.
Does anyone know how to do this?
Thanks,
Joe
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
