10 kwn=valuen
11
13 Set parameters in the header of a FITS or IRAF image. If the keywords
14 do not already exist, they are added at the end of the header. Values
15 are assumed to be numeric if they contain no alphabetic characters and
16 right-aligned. Otherwise they are left-aligned after the equals sign,
17 and padded by spaces to a minimum of 8 characters. To set keywords in
18 a list of files, substitute @<listfile> for the file names on the com‐
19 mand line. To set a lot of keywords, put them, one per line, in a file
20 and substitute @<keylistfile> on the command line. If two @ commands
21 are present, the program will figure out which contains file names and
22 which contains keywords. Lines in a keyword list file which do not
23 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 SETHEAD keyword into output header with sethead version,
31 current date and time, and names of keywords set. If a SETHEAD
32 keyword already exists, move the old value to a HISTORY line
33 before writing the new value
34 -n Write a new file with an added "e" before the extension.
36 -r letter
38 Rename existing keywords whose values are being reset by
39 prepending the character "letter". Drop the last character if
40 the changed keyword is already 8 characters long.
