fitsort - sort FITS header information from a list of files


dfits <FITS files...> | fitsort <FITS keywords...>


fitsort extract keyword values from a set of FITS headers and outputs it in an ASCII table
format, which is compatible with most data processing software packages. It shall only be
used in combination with the dfits utility.

The ASCII output is shown in columns. Columns are aligned with blank characters and also
separated by tabulations. Blank alignment allows human readers to visualize the output in
a pretty format, tabulations are there for spreadsheet compatibility. If you want to load
out fitsort output into any spreadsheet, specify that fields shall be separated by
tabulations and entries separated by linefeeds.

Examples :
dfits *.fits | fitsort BITPIX NAXIS NAXIS1 NAXIS2

The output would look like:
file0001.fits 16 2 128 128
file0002.fits 32 2 512 512

ESO specific features in the FITS header are also supported. To get values for 'HIERARCH
ESO' keywords, just give the complete names within double quotes. e.g.

dfits *.fits | fitsort "HIERARCH ESO INS LENS"

Another way of giving HIERARCH ESO keywords is to use the short FITS notation, the above
example can be given as:

dfits *.fits | fitsort INS.LENS

Example: to retrieve the DPR keywords from an ESO FITS header, you would use:

dfits *.fits | fitsort To be completed... DPR.CATG DPR.TYPE DPR.TECH

This second way of requesting HIERARCH ESO keywords is not only shorter to type, it also
avoids typing quotes or double-quotes on the command-line, making it easier to script with

Notice that the keywords you give on the command-line are case-insensitive. The above
line is equivalent to:

dfits *.fits | fitsort dpr.catg dpr.type dpr.tech


-d Do not print out the first output line. This option is useful to get only the query
results, without the top line (giving all column names). This makes it easy to
script fitsort from programs like awk or perl.
