host_type and host_prior

[bruholder]

Hello,

First of all, I want to express my great appreciation for this fantastic tool. I think it will be incredibly useful for astronomers worldwide.

I was trying to run the example notebook, but I ran into some issues during initialization. I should mention that I'm not very experienced in programming, so I apologize if I've misunderstood something simple.

When running the code to determine the number of broad components and fit of the galaxies, I encountered the following error:

From what I can tell, the problem seems to be that it can't find the reference files for the BC03 model.

I tried to look into the source code to understand the issue and I saw that in the definition of Fit, the default value for host_type is set to 'BC03':

But in the comments there is a statement that only PCA option is allowed if host_prior=True

When I manually changed the host_type parameter to 'PCA' in the example, everything seemed to work as intended.

Could you please clarify if this is the expected behavior, or if there might be a small oversight in the example or default configuration? I just wanted to bring this to your attention. I am using version 2.1.6

Thank you very much for your time and for creating this tool!

Sorry for the delay, yes, only the PCA allow prior to be True
