Retrieve all the data values stored in a column astGetColumnData
"
coldata"
for any cells for which no value has been stored in the FitsTable.
Ignored if the column’
s data type is not AST__FLOATTYPE. Supplying AST__NANF will
cause a single precision IEEE NaN value to be used. "
coldata"
for any cells for which no value has been stored in the FitsTable. Ignored if
the column’
s data type is not AST__DOUBLETYPE. Supplying AST__NAN will cause
a double precision IEEE NaN value to be used. "
coldata"
array, in bytes. The amount of memory needed to hold the data from a
column may be determined using astColumnSize. If the supplied array is too
small to hold all the column data, trailing column values will be omitted from
the returned array, but no error will be reported. "

order. No data type
conversion is performed - the data type of each returned value is the data
type associated with the column when the column was added to the table. If the
column holds strings, the returned strings will be null terminated. Any excess
room at the end of the array will be left unchanged. "
coldata"
array. This is the product of the number of
rows returned and the number of elements in each column value. The "
fnull"
and "
dnull"
parameters specify the value to be returned for any empty
cells within columns holding floating point values. For columns holding integer values,
the value returned for empty cells is the value returned by the astColumNull function.
For columns holding string values, the ASCII NULL character is returned for empty
cells.
