A life raft for ESO's old-school FITS tools

I fear change, and these are no longer available on ESO's website. I therefore am preserving them here.

dfits and fitsort — both beautifully written by Nicolas Devillard at ESO between 1996 and 2000 (!) — dumps and sorts (respectively) FITS header contents on the command line. They accept all the usual *nix shell stuff, allowing constructs such as:

dfits *.fits | grep OBJECT

dfits *.fits* | fitsort DPR.CATG PRO.CATG EXPTIME IMAGETYP

dfits *.fits* | fitsort DPR.CATG EXPTIME IMAGETYP | grep SCIENCE

To compile:

gcc -o dfits dfits.c

gcc -o fitsort fitsort.c

or

make; make install (thanks to Gabe Brammer for this makefile)
