Clouds analysis with the presence of the moon #38

Closed vbonvin closed 6 years ago

vbonvin commented 6 years ago

Currently, the moon on the allsky is detected as clouds. It will be hard to get rid of this with single-band images.

Let's keep this issue open to remind that we still need a fix for this, if possible

kuntzer commented 6 years ago

I fixed the Moon issue by dividing the all sky image by a gaussian filtered (with a large sigma, 10 by default) image of itself, thus removing the large structures of the image. This is akin dividing by a flatfield. The commit 618e19caa82103b5db9b9c5dab2816c435f01e6b includes those changes, but slows down the analysis of the image significantly, thus the issue #57.

Since , however, the moon issue is fixed, I close this.

PS: you can see the improvement by running python clouds.py
