24.3 CCfits::Column Class Reference 60
of indata equal to ∗nullValue. For integer type columns there must be a pre-existing
TNULLn keyword to define the FITS null value, otherwise a FitsError exception is
thrown. For floating point columns, the FITS null is the IEEE NaN (Not-a-Number)
value. See the cfitsio fits_write_colnull function documentation for more details.
Parameters
indata The data to be written.
firstRow The first row to be written
nullValue Pointer to the value for which equivalent indata elements will be replaced
in the file with the appropriate FITS null value.
24.3.3.22 template void CCfits::Column::write ( S ∗ indata, long nRows, long
firstRow, S ∗ nullValue )
write a C array into a scalar Column, processing undefined values.
Parameters
indata The data to be written.
nRows The size of the data array to be written
firstRow The first row to be written
nullValue Pointer to the value in the input array to be set to undefined values
24.3.3.23 template void CCfits::Column::write ( const std::valarray< S > &
indata, long nRows, long firstRow )
write a valarray of values into a range of rows of a vector column.
The primary use of this is for fixed width columns, in which case Column’s repeat
attribute is used to determine how many elements are written to each row; if indata.-
size() is too small an exception will be thrown. If the column is variable width, the call
will write indata.size()/nRows elements to each row.
Parameters
indata The data to be written.
nRows the number of rows to which to write the data.
firstRow The first row to be written
24.3.3.24 template void CCfits::Column::write ( const std::vector< S > &
indata, long nRows, long firstRow )
write a vector of values into a range of rows of a vector column
The primary use of this is for fixed width columns, in which case Column’s repeat
