Add a keyword to a crate.
add_key(crate, cratekey);
- crate - input crate
- cratekey - CrateKey object to be added
The add_key command adds the keyword to the end of the keyword
list in the crate. If the keyword already exists, the value
is replaced. The command returns a "1" if the keyword is
successfully added.
The keyword is only added to the crate. The write_file
("ahelp write_file")
command can be used to save the modified crate to a file.
slsh> cr = read_file("evt2.fits");
slsh> key = CrateKey();
slsh> key.name = "TIMEDEL";
slsh> key.load("0.00285");
slsh> key.unit = "s";
slsh> add_key(cr, key);
1
Create a new key named "TIMEDEL" with a value of 0.00285
and units of seconds, then add it to the crate.
