PUTTHEAD
Type: Verb
Use: PUTTHEAD is used to alter the contents of a keyword/value pair
in a table header. A limited number of new keywords may be
added.
Adverbs:
INNAME......Image name(name). Standard defaults.
INCLASS.....Image name(class). Standard defaults.
INSEQ.......Image name(seq. #). 0 => highest.
INDISK......Disk drive # of image. 0 => any
INEXT.......Table type. No defaults.
INVERS......Table version #. 0 => highest.
KEYWORD.....The FITS name of the parameter. No default.
KEYVALUE....The value to be given to an integer parameter if
KEYVALUE(1) and to a floating-point parameter is
KEYVALUE(1) + KEYVALUE(2). No default.
KEYSTRNG....The value to be given to a character parameter.
No default. If the first character is 'T', a logical
parameter will be treated as true.
KEYTYPE.....If a keyword is to be added to a catalog header then the
data type of the associated value must be specified.
The values 'D', C', 'I', and 'L' correspond to double
precision (used for all floating-point values),
character (up to 8 characters), integer and logical.
DOHIST......If < -1.5, the transaction will not be recorded in the
history file. Otherwise the previous and new header
values are put in the history file since this is a
potentially important operation.
