aflak 0.0.3

Advanced Framework for Learning Astrophysical Knowledge

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

• Improve ROI drawing

• Include GUI way of showing a fits header

• 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

v0.0.3

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.
