Handle complex multi-component sources in XML model generator #178

Closed mireianievas closed 1 year ago

mireianievas commented 1 year ago

Before:

Sources that are very close: assume it is the target source and add it at the beginning of the XML with free parameters.
Problem: Crab in 4FGL has Crab Nebula sync + Crab Nebula IC + Crab pulsar as 3 sources. Enrico analysis is done in just a single source (Crab 'total').

Now

If the input srcname is in the 4FGL, then that is the target source (e.g. J0534.5+2201i --> Crab Nebula IC). Other co-spatial sources (e.g. J0534.5+2201s or J0534.5+2200 --> Crab Nebula Sync and Crab Pulsar) are added too, but with FIXED parameters.
If the input srcname is not in the 4FGL, do the 'total' analysis with a single source as before.
