Details:

With Gnuastro 0.8.36
<https://lists.gnu.org/archive/html/info-gnuastro/2019-02/msg00000.html>, 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.
