Empymod

----------------------

**2018-02-24**

- Documentation:

- Simplifications: avoid duplication as much as possible between the website
(empymod.github.io), the manual
(`empymod.readthedocs.io <https://empymod.readthedocs.io>`_), and the
``README`` (github.com/empymod/empymod).

- Website has now only *Features* and *Installation* in full, all other
information comes in the form of links.
- ``README`` has only information in the form of links.
- Manual contains the ``README``, and is basically the main document for
all information.

- Improvements: Change some remaining ``md``-syntax to ``rst``-syntax.

- FHT -> DLF: replace FHT as much as possible, without breaking backwards
compatibility.

-----------------------------------

**2018-01-02**

- Minimum parameter values can now be set and verified with
``utils.set_minimum`` and ``utils.get_minimum``.

- New Hankel filter ``wer_201_2018``.

- ``opt=parallel`` has no effect if ``numexpr`` is not built against Intel's
VML. (Use ``import numexpr; numexpr.use_vml`` to see if your ``numexpr`` uses
VML.)

- Bug fixes

- Version of manuscript submission to geophysics for the DLF article.


v1.4.x
""""""

--------------------

**2017-09-18**

[This was meant to be 1.4.3, but due to a setup/pypi/anaconda-issue I had to
push it to 1.4.4; so there isn't really a version 1.4.3.]

- Add TE/TM split to diffusive ee-halfspace solution.

- Improve ``kernel.wavenumber`` for fullspaces.

- Extended ``fQWE`` and ``fftlog`` to be able to use the cosine-transform. Now
the cosine-transform with the real-part frequency response is used internally
if a switch-off response (``signal=-1``) is required, rather than calculating
the switch-on response (with sine-transform and imaginary-part frequency
response) and subtracting it from the DC value.

- Bug fixes

-----------------------------------------------------

**2017-06-04**

- Bugfix: Fixed squeeze in ``model.analytical`` with ``solution='dsplit'``.

- Version of final submission of manuscript to Geophysics.

--------------------------------------------

**2017-05-30**

[This was meant to be 1.4.0, but due to a setup/pypi/anaconda-issue I had to
push it to 1.4.1; so there isn't really a version 1.4.0.]

- New home: empymod.github.io as entry point, and the project page on
github.com/empymod. All empymod-repos moved to the new home.

- /prisae/empymod -> /empymod/empymod
- /prisae/empymod-notebooks -> /empymod/example-notebooks
- /prisae/empymod-geo2017 -> /empymod/article-geo2017
- /prisae/empymod-tle2017 -> /empymod/article-tle2017

- Modelling routines:

- New modelling routine ``model.analytical``, which serves as a front-end to
``kernel.fullspace`` or ``kernel.halfspace``.
- Remove legacy routines ``model.time`` and ``model.frequency``. They are
covered perfectly by ``model.dipole``.
- Improved switch-off response (calculate and subtract from DC).
- ``xdirect`` adjustments:

- ``isfullspace`` now respects ``xdirect``.
- Removed ``xdirect`` from ``model.wavenumber`` (set to ``False``).

- Kernel:

- Modify ``kernel.halfspace`` to use same input as other kernel functions.
- Include time-domain ee halfspace solution into ``kernel.halfspace``;
possible to obtain direct, reflected, and airwave separately, as well as
only fullspace solution (all for the diffusive approximation).


v1.3.x
"""""""

-------------------------------------------------------

**2017-03-30**

- Add additional transforms and improve QWE:

- Conventional adaptive quadrature (QUADPACK) for the Hankel transform;
- Conventional FFT for the Fourier transform.
- Add ``diff_quad`` to ``htarg``/``ftarg`` of QWE, a switch parameter for
QWE/QUAD.
- Change QWE/QUAD switch from comparing first interval to comparing all
intervals.
- Add parameters for QUAD (a, b, limit) into ``htarg``/``ftarg`` for QWE.

- Allow ``htarg``/``ftarg`` as dict additionally to list/tuple.

- Improve ``model.gpr``.

- Internal changes:

- Rename internally the sine/cosine filter from ``fft`` to ``ffht``, because
of the addition of the Fast Fourier Transform ``fft``.

- Clean-up repository

- Move ``notebooks`` to /prisae/empymod-notebooks
- Move ``publications/Geophysics2017`` to /prisae/empymod-geo2017
- Move ``publications/TheLeadingEdge2017`` to /prisae/empymod-tle2017

- Bug fixes and documentation improvements
