✨ Quick Start

CLFits provides a straightforward, command-based interface for header manipulation.

View the entire header:

clfits view my_image.fits

Get the value of a specific keyword:

clfits get my_image.fits OBJECT

Set a keyword's value and comment:

clfits set my_image.fits OBJECT "NGC 4993" --comment "Corrected object name"

Delete a keyword:

clfits del my_image.fits HISTORY

Export the header to JSON:

clfits export my_image.fits --format json

Export the header to a YAML file (format is inferred from filename):

clfits export my_image.fits --output header.yml

Search for all keywords related to the observation date:

clfits search my_image.fits --key "DATE*"
