AttributeError in scousefitter when ncomps>8 is detected

[AkshayaMS]

Hello,

I am using scousepy for the Galactic center data which has multiple components (some regions ncomps > 8). I noticed there is an error which recurs when I do the manual fit or when I use the interactive sliders to change the alpha or SNR. The total model, residuals and components are never drawn after this even with manual fits. I am attaching the screenshot below.

The manual fits are saved I think, but the plots don't get updated. The changes in alpha reduces the components to less than 8 but dspec doesn't work once the initial detected components were greater than 8.

I tried to find out what was the issue and tested the code with different datasets. This only happens when ncomps > 8. I did a temporary fix by changing the condition in scousefitter.py (line 1198) from:

if self.dsp.ncomps < 8:
    update_text(self.text_fitinformation,'pyspeckit fit information: ')

to

if self.dsp.ncomps < 15:
    update_text(self.text_fitinformation,'pyspeckit fit information: ')

I don't encounter the issue after this change. Everything works well (sample below).

Also, the manual fitting doesn't work with matplotlib versions > 3.5.3. Just a heads up in case someone encounters the same issue.
