Composite SNRs

[cdeil]

As discussed in the telcon today, we want to couple ~ 1/3 of the PWN and SNRs as composites.

For position it's very easy, we just take the same one for that fraction of sources.

So how to choose the PWN parameters in the composites?

• Take the age from the SNR model by Pierre
• For physical size, this might be useful:
  • http://docs.gammapy.org/en/latest/astro/source/pwn.html (SNR and PWN radius labels are switched, will fix now)
• http://pubman.mpdl.mpg.de/pubman/item/escidoc:912132:1/component/escidoc:912131/BScThesis_ddonath.pdf

For spectral PWN parameters, there is no good model or obvious solution what to put. @robertazanin might make a suggestion based on the HESS PWN population paper. Or we keep spectra as-is and don't couple PWN and SNR spectra for the composites.

We can use this issue to discuss and make it's done before we put out the final sky model.

This was implemented today by @robertazanin and all generated files / plots are updated now.

I didn't change the plots yet to show COMP sources separately, or to do any checks specifically to show if COMP sources have good parameters.
