This would become obsolete and can be closed if we ever decide to require scipy (https://github.com/sherpa/sherpa/issues/786) scipy that has equivalent integration functions (the integration functions in the GSL bundeled with...

(Note that `fake_pha` already has this capability, but with the following code: ``` if rmf is None: raise DataErr('normffake', id) if type(rmf) in (str, numpy.string_): if os.path.isfile(rmf): rmf = self.unpack_rmf(rmf)...

I looked at some of those. I might be possible to get some of the other to behave the same way, but I think it's less pressing for the others,...

And `set_arf` and `set_rmf` can continue to be the advertised way in the docs, they would just be implemented as an alias or thin wrapper around `load_arf/rmf`

I think that latter is another manifestation of #1602 ```Python for i in range(5): print(i, histogram1d([0, 1, 2, 3], [0, 1, 2], [1, 2, i])) 0 [1 1 1] 1...

In other words: We need a better error message.

I suggest to write a good example for this to add top the docs on advance customization.

I was going suggest to simply change `.16g` to `16g`. That way, we get up to 16 digits (with trailing zeros removed). For the most common type of number in...

I think if you bot good to have one 3D Kernel that can be looked at as an example for users intending to implement their own. It can be very...

Personally, I think this could live in the docs, with somewhat expanded comments on the individual methods. But let's wait for the modelling maintainers to weigh in before we make...
