FITS Metadata Extractor

Description

This Python script extracts metadata from FITS (Flexible Image Transport System) files, commonly used in astronomy. It reads the file, gathers metadata from each Header/Data Unit (HDU), and outputs it in a readable format.

Features

  • Extracts and displays metadata from all HDUs in a FITS file.
  • Option to pretty-print the output for enhanced readability.

Usage

Run the script with the path to a FITS file:

./fits_extract.py path/to/your/fits_file.fits

pipenv run python fits_extract.py

For a pretty-printed JSON output:

./fits_extract.py path/to/your/fits_file.fits --pretty

For help

./fits_extract.py --help

Requirements

  • Python 3
  • Astropy package (install via pip install astropy)
