NAME

ft_cardpar,ft_cardget,ft_cardgetl,ft_cardgeti,ft_cardgetr,ft_cardgets -Fitsy FITS card parsing routines.

SYNOPSIS

char *ft_cardpar(FITSCard card, FITSType *type, char *value, int *index, char *comm);
char *ft_cardget(FITSCard card);
int ft_cardgetl(FITSCard card);
int ft_cardgeti(FITSCard card);
double ft_cardgetr(FITSCard card);
char *ft_cardgets(FITSCard card);

• FITSCard card - FITS card to parse.
• FITSType *type - Returned card type.

  Possible values for a FITSType are as follows:

  • FT_COMMENT
  • FT_LOGICAL
  • FT_INTEGER
  • FT_STRING
  • FT_VALUE
  • FT_REAL
  • FT_COMPLEX

• char *value - Returned card value string.
• int *index - Returned index of the card keyword.
• char *comm - Returned card comment.

These routines parse FITS cards. Usually the header value routines will be used instead of these.

ft_cardpar

Parse a FITS card in to its type, value index and comment parts

The ft_cardpar will parse an 80 character fits card in memory into its parts according to the standard. Some non-standard card formats are recognized.

ft_cardget

Return the value of a FITS card in a static buffer.

ft_cardgetl

Return the value of a FITS card as a logical.

ft_cardgeti

Return the value of a FITS card as a integer.

ft_cardgetr

Return the value of a FITS card as a double.

ft_cardgets

Return the value of a FITS card as a allocated string.

The returned string is allocated with strdup().

RETURNS

The value parameter.

EXAMPLES

                FITSHead        fits;
                FITSCard        card;
                FITSType        type;
                char            value[FT_CARDLEN];
                int             index;
                char            comment[FT_CARDLEN];

                int             im;     /* Is this a primary image? */

        ft_cardpar(card, &type, value, &index, comm);

        card = ft_headfind(fits, "SIMPLE", 0, 0);

        im = ft_cardgetl(card);
