So they are related to the date, assuming `e_overestim = 10`.

This carries more information.

This variable was already used in other tests.

Because some tests require results from other tests in this series of
tests.

We now want the default behaviour to be renumber. `SHPC_class` expects
sequential eddy indices from 1.

Instead of using old result from Matlab. And run on cyclones instead
of anticyclones, why not, just one less entry in the namelist.

Because it can be created by analysis scripts.

The corresponding modules are not used in the functions.

This was polluting standard output. So we have to add the shapefile
path when it is not found.

OSError is more specific than SystemExit. It is better to have a more
specific exception when we want to catch it.

Invert order of dummy arguments orientation and layer of method
`get_reader`. Take the same order than in the path. `orientation` was at
the end because, at first, in commit d858fb72, it was an optional
argument.

It must be the same than the one used for other input files of the test.

Remove input file `outside_points_get_1_outerm.csv`. Use result from
test `Region_1_20454_cyclone_3` instead. There is one less point in
the file `outside_points.csv` from the test `Region_1_20454_cyclone_3`
but this does not change the results of the two impacted tests:
`Get_1_outerm` and `Extr_proj`.

The only difference in the test specification of
`Get_1_outerm_noise_2` with test `Get_1_outerm` is the input file
`outside_points.csv`. This difference in specification leads to no
difference in results of the two tests. The input file
`outside_points.csv` for `Get_1_outerm` is problematic because it has
an extra point at (9.375, -35.857) which corresponds to a cyclone for
an old version of SSH data. So we are going to change the input file
of `Get_1_outerm` to take
`$tests_old_dir/Region_1_20454_cyclone_3/outside_points.csv`, the same
one than for `Get_1_outerm_noise_2`, so there is really no use for
`Get_1_outerm_noise_2`.

Remove input file `outside_points_get_1_outerm_noise_2.csv`. Use
result from test instead.

Motivation: provide file `outside_points.csv` instead of keeping it in
`Inst_eddies/Tests/Input/Region_1`.

To new version provided by Aviso.

There is no significant difference with
`Extraction_eddies_region_1_noise`: no impact of `min_amp` on this
region. For an impact of `min_amp`, compare tests
`Extraction_eddies_region_3` and `Extraction_eddies_region_3_min`.
