|AHELP for CIAO 4.2||
Add a keyword to a crate.
- 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.
>>> cr = read_file("evt2.fits") >>> key = CrateKey() >>> key.name = "TIMEDEL" >>> key.load("0.00285") >>> key.unit = "s" >>> 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.
