6 keyhead - Change FITS or IRAF header keyword names
7
9 sethead [-hknv] <FITS or IRAF file> kw1=kw1a kw2=kwd2a ... kwn=kwdna
10
12 Change the names of keywords in FITS or IRAF image headers. Each cur‐
13 rent image keyword whose entry is to be modified should be followed by
14 an equal sign and a second keyword, with no intervening spaces. If the
15 -r option is used, the value of the second keyword is transfered to
16 that of the first. Otherwise, the name of the first keyword is changed
17 to the second keyword. To change keywords in a list of files, substi‐
18 tute @<listfile> for the file names on the command line. To change a
19 lot of keywords, put them, one pair separated by an = sign with no spa‐
20 ces per line, in a file and substitute @<keylistfile> on the command
21 line. If two @ commands are present, the program will figure out which
22 contains file names and which contains keywords. Lines in a keyword
23 list file which do not contain an = are ignored.
24
27 -h Write HISTORY line into output header with sethead version, cur‐
28 rent date and time, and names of keywords set.
29 -k Write KEYHEAD keyword into output header with the keyhead ver‐
31 sion, current date and time, and names of keywords whose names
32 are changed. If a KEYHEAD keyword already exists, move the old
33 value to a HISTORY line before writing the new value
34 -n Write a new file with an added "e" before the extension.
36 -r letter
38 Replace value of 1st keyword with value of 2nd keyword instead
39 of changing the name of the 1st keyword to the 2nd keyword. The
40 2nd keyword remains in the header. If the 1st keyword does not
41 exist in the header, it is created.
42 -v Print confirmations of each keyword change.
