Carlos Morales Socorro reported that we were mistakenly referring to
the magnitdue column with '$1', but it should have been '$4'.

Carlos suggested this link. Its good that we also keep a list of other
similar resources here.

The supercomputing SMACK was moved ahead.

With this commit, I am adding the link to the recorded video in Youtube,
and a link to the Vim tips wiki. Also a detailed description on how to
add text using Vim visual block mode has been included.

An example copyright statement was added as an item to explain.

With this commit, several minor typos have been corrected. Also some
very basic Vim options have been added.

Some minor issues were found and fixed

A first draft of the steps to highlight in the SMACK on shell
scripting have been added. I also added the YouTube link of the third
SMACK on Gnuastro.

There was a minor grammatical error. Also, the new edit makes it
easier to read.

During SMACK-3 that was presented today, Joseph Putko also presented
some steps that are now included in the main lecture notes.

Since the talk has been completed, they are no longer relevant and may
confuse viewers. We used them to mark who should present which part of
the talk.

Until this commit, there were some minor typos in this tutorial. With
this commit, they have been fixed. I also added a couple of useful
commands in the `astarithmetic' part. I think people will be interest in
masking not only 1 or 0 but any other particular values from the mask
image.

Until now, Mohammad's parts of SMACK-3 weren't complete and organized
with the rest. So with this commit, I went through them once and put
them in the same context as the rest.

The difference between the PC matrix elements of the input was
described in more detail, and for the outputs of Segment when seen
with astfits, we mention to look in the DS9 command afterwards.

Since there was some over-lapping parts, the conflicts are now fixed
and it is in an almost smooth part. I have also done an initial
classification of the steps for Raul and myself.

With this commit, I have included the rest of programs we planned to
show in this talk. They correspond to NoiseChisel, Segment, Makecatalog,
Match, etc.

From the guide, this should help show it properly.

Apprently Gitlab's Markdown allows embedded YouTube links, so I am
trying it out here.

Some details were added to the first steps and the over-all style was
set with less indentation (so Gitlab shows the codes properly).

With this commit, the first steps of the SMACK-3 tutorial have been
added. They correspond to the download of the data and how to use:

 - ds9, for looking at the data
 - astfits, for having a look at the image info/headers
 - astcrop, for selecting regions
 - noisechisel, for detecting signal

This is only the very first steps, so they could be modified.

With this commit, a description for some parts of the working scenario has
been added.

SMACK-3: Setting main steps and commands to be explained

See merge request !2

After a first talk, we set the main steps to be explained in this talk.

A summary for the Gnuastro SMACK has been added.

It is more easily readable now.

Since its URL is now recorded, having a link to it can help with
someone who is new to it.

Since the talk is now recorded it was useful to add the link here.

Since the talk has been done now, there is no more need to mention the
name of the speakers on each item.

I had forgot to mention that the third command should also be ignored.

By default cURL doesn't actually save the downloaded file, it just
prints it to standard output. So I modified the explanation to reflect
this.

With this commit, the direction for downloading the catalogue UVUDF used
in `smack-2-shell.md' has been corrected. There was an underscore
instead of a dash in the name of the file.

On some computers, wget isn't available, so we are suggesting curl
instead.

Since it has many unreasonable decimals.

The `-e' was removed and instead of world, we now have IAC ;-).

Some explanation was added for Info and Man-pages. And to help in
readability, the `while' command is now fed through a simple pipe.

Also, when generating random numbers, I show how to put a random
column in a catalog and also how to format the output with AWK.

Bash's `$RANDOM' is only for integers and isn't too robust, but AWK's
is much better and useful for floating points too.
