I know that the PSF stuff is a little bit different than other model components (eg `gauss2d`) but shouldn't the `.pars` return the list of parameters?
```python
sherpa In [1]: load_data("fi/out_b…

When trying to set a model to described the instrument background without knowing the background IRFs I get the following error

I realised that I never really documented this enhancement.
Currently sets of annular spectra have 'normal' ARFs generated for each spectrum of each annulus, without regard for PSF effects that can…

We can link the parameters of model, e.g. `g2.pos = g1.pos + 0.125`. We can also set the max and min of a parameter, e.g. `g2.pos.max = 11.234`. However, I can't set a parameter bound to be related to…

# Description
The user extracted the spectrum with specextract, then used FTools' GRPPHA to bin the spectrum to at least five counts per bin and flag specific channels as bad (1-35,501-1024).

It is perhaps known issue. I was just trying to input a radial profile of the psf as a table model and the file is not found/read with the syntax which is perfectly ok in the CIAO sherpa. I'm using th…

On paper, Sherpa and XSpec do not allow the channel range of the spectrum and that defined in the RMF to differ, although I've been able to get models to fit in Sherpa with a channel mismatch. Downst…

I added `--verbose` to the `pytest` command so we can see where the segfault happens (I know, from doing this dance …
