With Gnuastro 0.8.36, a major NoiseChisel bug was fixed, resulting in better results with the default NoiseChisel parameters.

However, we had forgot to update the tutorials after this change. After a recent run of the command in the tutorial, I saw that the result isn't what was expected.

After some trials with the new NoiseChisel, I found the following parameters to give a roughly equal result:

astnoisechisel sdss.fits -h0 --tilesize=75,75 --meanmedqdiff=0.001 --interpnumngb=6 --qthresh=0.2 --detgrowquant=0.65 --detgrowmaxholesize=10000

The tutorial should be edited to correct this issue.
