aflak 0.0.6

===============================================================
aflak - Advanced Framework for Learning Astrophysical Knowledge
===============================================================

.. figure:: https://api.travis-ci.org/malikolivier/aflak.svg?branch=master
:alt: Build status

Environment
===========

Support Python3.

Setup
=====

::

virtualenv -p python3 venv
. ./venv/bin/activate
pip install -r requirements.txt

Open a FITS file
================

::

./run my-fits-file.fits

The provided FITS file is required to have the following extensions:

- 'FLUX': 3D data containing 2D luminosity component for each wavelength value
- 'WAVE': 1D data containing value of each target wavelength

After some fiddling you should be able to get a window like below:

Get sample FITS files
=====================

The Makefile contains a few recipes to get sample fits files.
Run make as below:

::

make data/manga-7443-12703-LINCUBE.fits

To see a fits file header
=========================

::

fold -w 80 foo.fits | less

TODO
====

- Show arbitrary sums over spectral data (currently only show one frame)
- Benchmark / Test with several fits files
- Set a label on the histogram's Y-axis (flux [1E-17 erg/s/cm^2])
- Add a compass showing North and East directions and a scale bar in the unit
of arcsec on the image

v0.0.6
======

New:

- Make .deb files for easy distribution

Fix:

- Force use of PyQt5, even if PyQt4 happen to be installed (28cb7a0)
- Increase size of ROI handles, making them easier to be grabbed (e533168)


v0.0.5
======

New:

- Add 3 types of ROI: polygonal, ecliptic and semi-automatic. In semi-automatic
mode, the use is free to choose and point and a threshold. All the points
above the threshold around the selected point will be inside the ROI.
- Add a "Recent Files" menu. No need to look far away for your FITS files.

Change:

- Delete ROI button and move ROI management inside menu.

Fix:

- Output of --version under some some circumstances (fa7e211)
- Name of main window is set to 'aflak' (6677775)


v0.0.4
======

New:

- FITS menu from which FITS header can be seen
- Version flag to CLI
- `About' dialog box in Help menu


v0.0.3
======

Fix: Run aflak as module (with `python -m aflak`)

New:

- Include some unit tests
- Include units in waveform axes, read from loaded FITS files


v0.0.2
======

Fix: Use logarithmic scale on brightness histograms


v0.0.1
======

Very first version released on PyPI. Can only open FITS files and visualize
FLUX and WAVE data.
