Fail to fit when adding x-ray photometry

[ChengLinLiao]

Hi all,

I add three x-ray photometry in the original photometry sets from optical to radio, but it turns out that X-CIGALE fail to fit. The output from the terminal shows

Sanity check of the analysis results...
No suitable model found for AS2COS0066.1. It may be that models are older than the universe or that your χ² are very large.
0.0% of the objects have χ²_red~0 and 0.0% χ²_red<0.5

I've checked the output files, and there are no any value in the “best_model.fits” file. The best-fit age of oldest stars is only 500 Myr, shorter than the age of Universe, and the reduced_chi_square is a null value from the fitting. How could I move on and fix the problem?

Another question is that why some x-ray pivot wavelengths in the filter list are zeros?

Thanks in advance,
Cheng-Lin Liao

Could you share your input data and pcigale.ini file? The pivotal wavelength *displays* as 0 because of rounding. It's actually not 0.

Thanks @Guang91 .
I've solved the problem, and I found that is because I forgot to include the xray module.
Now X-CIGALE runs successfully.

Okay, glad you solved it. Let me know if you have further questions.

No other questions. Thanks.
