This routine reads a keyword of any kind from a FITS header. It is a wrapper to
other routines that read keywords of different kinds.

header, kwd, value, comment
)

|
header(LEN=80) DIMENSION(:) |
CHR |
IN |
The header to read the keyword from. |
| kwd(LEN=8) |
CHR |
IN |
the FITS keyword to read (NOT case sensitive). |
| value |
any |
OUT |
the value read for the keyword.
The type of the fortran variable 'value' (double, real, integer, logical or
character) should match the type under which the
value is written in the FITS file, except if
'value' is a character string, in which case it can read any
keyword value, or if 'value' if real or double, in which case
it can read any numerical value |
| comment(LEN=*) |
CHR |
OUT |
comment read for the keyword. |
EXAMPLE:
call get_card(header,'NsIdE',nside,comment)
if nside is defined as an integer, it
will contain on output the value of NSIDE (say 256) found in header
EXAMPLE:
call get_card(header,'ORDERING',ordering,comment)
if ordering is defined as an character string, it
will contain on output the value of ORDERING (say 'RING') found in header
