This code creates skeleton VTF FITS files with headers that are compliant with the YAML files in the DKIST fits-validator package. The files contain no image data.
Requirements:
- fits-validator
- pyyaml
- astropy
Set up an environment with python (must be version >=3.7) and ensure the required libraries are installed:
pip install fits-validator pyyaml astropy
Then copy the generate_vtf_fits_file.py script to your machine and run it with
python generate_vtf_fits_file.py
You can modify the values or add new keywords by using the command
hdu.header['keyword_name'] = VALUE
in the section of the code where a number of examples have already been provided.
Running the script
>>> python generate_vtf_fits_file.py
File example_vtf_file.fits created.
