Roman SNPIT fork of SFFT
------------------------

Please look at the PyPi package ``sfft`` for the original.  This
package has customizations created for the Roman SNPIT.

Saccadic Fast Fourier Transform (SFFT) is an algorithm for fast & accurate image subtraction in Fourier space. 
SFFT brings about a remarkable improvement of computational performance of around an order of magnitude compared to other published image subtraction codes. 

SFFT method is the transient detection engine for several ongoing time-domain programs, including the `DESIRT <https://ui.adsabs.harvard.edu/abs/2022TNSAN.107....1P/abstract>`_ survey based on DECam & DESI, the DECam GW-MMADS Survey for GW Follow-ups and the JWST Cycle 3 Archival program `AR 5965 <https://www.stsci.edu/jwst/science-execution/program-information?id=5965>`_. SFFT is also the core engine for the differential photometry pipeline of the `Roman Supernova PIT <https://github.com/Roman-Supernova-PIT>`_.

Roman SNPIT Variant Notes
-------------------------

(These notes are for members of the Roman SNPIT who need to upload a new
version of this package.)

* Make sure that ``NAME`` in ``setup.py`` is ``sfft-romansnpit``.

* Make sure that VERSION in ``setup.py`` is of the form
``<MAJOR>.<MINOR>.<PATCH>.dev<n>`` where ``<MAJOR>``,
``<MINOR>``, AND ``<PATCH>`` match the upstream that has most recently been
merged in, and ``<n>`` is an integer that can start at 0 for a given
``MAJOR.MINOR.PATCH`` and that needs to increment each time we want to
push a new package.

* Build in the main directory with::

    python -m build --sdist --outdir dist

  That will create a file in ``dist`` named
  ``sfft_romansnpit-<version>.tar.gz`` where ``<version>`` is what you
  put in the ``VERSION`` variable.

* You can then upload it to the ``sfft-romansnpit`` package on PyPi with::

    twine upload dist/sfft_romansnpit-<version>.tar.gz
