dfits

Display FITS headers on stdout with dfits.

This command acts as a standard Unix filter: it takes a list of FITS file names in input and outputs their headers to stdout. Convenient to browse headers in directories. See fitsort to classify data from a list of FITS headers produced by dfits.

dfits can find informations in the main header (default), in the extensions, or in both. See the -x option to request information from a specific extension only, or from all headers in the file.

• dfits manual page
• dfits.c

Examples:

Display all headers, including extension headers:
% dfits -x 0 image.fits

Display only the main header:
% dfits image.fits

Display only extension header number 3:
% dfits -x 3 image.fits
