Ploonetide

===================

- Introduced a new layout for the
`online documentation <https://docs.lightkurve.org>`_. [#360, 400, 406]

- Added ``LightCurve.interact_bls()``: an interactive Bokeh widget to find
planets using the Box Least Squares (BLS) method. [401]

- Added ``LombScarglePeriodogram`` and ``BoxLeastSquarePeriodogam`` sub-classes
to distinguish periodograms generated using different methods. [403]

- Added the ``PLDCorrector`` class to remove instrument systematics using the
Pixel Level Decorrelation (PLD) method. [305]

- Added the ``TargetPixelFile.to_corrector()`` convenience method to make
systematics correction classes easy to access. [305]

- Refactored ``SFFCorrector`` to make its API consistent with ``PLDCorrector``,
and deprecated the ``LightCurve.correct()`` method in favor of
``LightCurve.to_corrector()``. [408, 417]

- Made ``SFFCorrector`` robust against light curves that contain big gaps in
time. [414]

- Minor bug fixes. [392, 397, 420]

- Increased the unit test coverage. [387, 388]

===================

- The ``TargetPixelFile.interact()`` bokeh app now includes a ``Save Lightcurve``
button [329].

- Fixed a minor bug in ``LightCurve.bin()`` [377].

===================

- Added support for TESS to ``search_targetpixelfile()`` and
``search_lightcurvefile()`` [367].

- Added support for data generated by the
`TESScut service <https://mast.stsci.edu/tesscut/>`_ [#369, 375].

- Removed "Impulsive outliers" from the default set of quality constraints
applied to TESS data [374].

- ``LightCurve.flatten()`` is now more robust against outliers [372].

- ``LightCurve.fold()`` now takes a ``transit_midpoint`` parameter instead of
the ``phase`` parameter [361, 363].

- Various minor bugfixes [372].

===================

- ``TargetPixelFile.create_threshold_mask()`` now only returns one contiguous
mask, which is configurable using the new ``reference_pixel`` argument [345].

- ``TargetPixelFile.interact()``: now requires ``Bokeh v1.0`` or later [355].

- ``utils.detect_filetype()`` automatically detects Kepler or TESS Target Pixel
Files and Light Curve files [340, 350, 356].

- ``LightCurve.estimate_cdpp()``: the argument ``sigma_clip`` was renamed into
``sigma`` [359].

- Fixed minor bugs in ``LightCurve.to_pandas()`` [343],
``LightCurve.correct()`` [347], ``FoldedLightCurve.errorbar()`` [352],
``LightCurve.fold()`` [353].

- Documentation improvements [344, 358].

- Increased the unit test coverage [351].

===================

- ``lightkurve.open()`` was added to provide a single function to read in any
light curve or target pixel file from Kepler or TESS and return the appropriate
object [317].

- The ``from_fits()`` methods have been deprecated in favor of
``lightkurve.open()`` [336].

- The ``lightkurve.mast`` module has been removed in favor of the new
``lightkurve.search`` module.

- Various small bugfixes, speed-ups, and documentation improvements
[314, 315, 322, 323, 325, 331, 334, 335].

===================

- The ``from_archive()`` methods of ``KeplerTargetPixelFile`` and
``KeplerLightCurveFile`` have been deprecated in favor of the new
``search_targetpixelfile()`` and ``search_lightcurvefile()`` functions.
These allow users to inspect the results of their queries and offer more
powerful features, e.g. cone-searches. If you are currently using
``tpf = KeplerTargetPixelFile.from_archive("objectname")``, please start
using ``tpf = search_targetpixelfile("objectname").download()`` instead.

- ``TargetPixelFile`` objects can now be indexed and sliced. [308]

- The default number of ``windows`` used by the SFF systematics removal
algorithm has been changed from 1 to 10. [312]

- Various small bug fixes and unit test improvements.
