sethead(1) General Commands Manual sethead(1)Name
sethead - Set FITS or IRAF header keyword values
Synopsis
sethead [-dknv][r letter] <FITS or IRAF file> kw1=val1 kw2=val2 ... kwn=valuen
Description
Set parameters in the header of a FITS or IRAF image. If the keywords do not already exist, they are added at the end of the header. Val-
ues are assumed to be numeric if they contain no alphabetic characters and right-aligned. Otherwise they are left-aligned after the equals
sign, and padded by spaces to a minimum of 8 characters. To set keywords in a list of files, substitute @<listfile> for the file names on
the command line. To set a lot of keywords, put them, one per line, in a file and substitute @<keylistfile> on the command line. If two @
commands are present, the program will figure out which contains file names and which contains keywords. Lines in a keyword list file
which do not contain an = are ignored.
Options-h Write HISTORY line into output header with sethead version, current date and time, and names of keywords set.
-k Write SETHEAD keyword into output header with sethead version, current date and time, and names of keywords set. If a SETHEAD key-
word already exists, move the old value to a HISTORY line before writing the new value
-n Write a new file with an added "e" before the extension.
-r letter
Rename existing keywords whose values are being reset by prepending the character "letter". Drop the last character if the changed
keyword is already 8 characters long.
-v Print confirmations of each parameter setting
