916 | * will be appended to the FITS file. In case that a different HDU type | |||
917 | * exists at the requested extension number, the existing HDU will be | |||
918 | * deleted and be replaced by the requested table type. | |||
919 | * | |||
920 | * The method also verifies the consistency of all table columns. Table | |||
921 | * columns need to have identical lengths to be saved into a FITS table. | |||
922 | * All columns with a length of zero will be excluded from saving, and if | |||
923 | * they exist in the FITS file, they will be removed from the file. | |||
924 | * | |||
925 | * @todo This method should also update the header. Even easier, this method | |||
926 | * should save the header into the file using the m_header.save() | |||
927 | * method. | |||
928 | * Only this assures coherence between the files !!!! Once this has | |||
929 | * been implemented (also in the GFitsImage method) we should delete | |||
930 | * the m_header.save() call in GFitsHDU::save. | |||
