Introduction

on Ubuntu 18.04.
What is python3-pyfits
python3-pyfits is:
FITS (Flexible Image Transport System) is a data format most used in astronomy. PyFITS is a Python module for reading, writing, and manipulating FITS files. The module uses Python’s object-oriented features to provide quick, easy, and efficient access to FITS files. The use of Python’s array syntax enables immediate access to any FITS extension, header cards, or data items.
Note that the development of PyFITS has been stopped and will not see any new
upstream version. It is superseded by the module astropy.io
which is almost
a drop-in replacement. PyFITS should therefore only be used for compatibility
reasons, astropy should be used instead for new developments.
This package provides PyFITS on the Python 3 module path. It is complemented by python-pyfits.
