Faster all sky image analysis

[kuntzer]

For now, it is embarrassingly slow. Find what is causing this and fix it.

[kuntzer]

It is really slow. Must be fixed for version 0.3

[kuntzer]

Fixed it by doing less iterations when trying to measure the FWHM of the stars by fitting a Gaussian.

To go even faster, should use other ways of measuring FWHM, but I think it's acceptable now.

I got an error message related to this:

  File "/home/vivien/work/pouet/pouet/clouds.py", line 98, in update
    x, y = self.detect_stars()
  File "/home/vivien/work/pouet/pouet/clouds.py", line 122, in detect_stars
    image /= filters.gaussian_filter(np.nan_to_num(image), 10)
TypeError: unsupported operand type(s) for /: 'NoneType' and 'NoneType'

It worked for a few allsky refreshes and then crashed.

that's extremely weird. Do you have more info on this? I'll run pouet for a while and see if I can reproduce

[vbonvin]

Nope. Currently having pouet running as well but it's stable so far. 2018-07-06 9:31 GMT+02:00 kuntzer <notifications@github.com>:

[kuntzer]

Could not reproduce, added a fail safe at the line in question. It will be considered as an error in the log. Will close this issue for now. Re-open if it happens again.

[vbonvin]

OK. Same here, didn't happen again.
