Assignment File Format ====================== XTDS packages provides the possibility to fit hamiltonian parameters using experimental data. This necessitates an assignment file containing lines of the following form (the format must be respected): .. code-block:: ..................................................................................... 7466 870.614507 + 0.2150E+00 0.001000 10.0 13 F2 3 12 F1 15 SPVIEW_EXASG 7467 870.620029 + 0.1490E+00 0.001000 10.0 13 E 2 12 E 11 SPVIEW_EXASG 7468 870.625041 + 0.2430E+00 0.001000 10.0 13 F1 4 12 F2 16 SPVIEW_EXASG 7469 870.644365 + 0.5500E-01 0.001000 10.0 9 A1 1 10 A2 2 SPVIEW_EXASG 7470 870.669249 0.1660E+00 0.001000 10.0 7471 870.674772 0.1150E+00 0.001000 10.0 7472 870.679803 0.1930E+00 0.001000 10.0 7473 870.784119 0.3700E-01 0.001000 10.0 7474 870.985433 0.3100E-01 0.001000 10.0 7475 871.024952 0.2200E-01 0.001000 10.0 7476 871.038518 0.3900E-01 0.001000 10.0 7477 871.065933 0.4200E-01 0.001000 10.0 7478 871.246246 0.2300E-01 0.001000 10.0 7479 871.341410 0.2300E-01 0.001000 10.0 7480 871.426834 0.6400E-01 0.001000 10.0 7481 871.485324 0.1240E+00 0.001000 10.0 7482 871.716760 0.3600E-01 0.001000 10.0 7483 871.891580 + 0.5300E-01 0.001000 10.0 24 F1 2 25 F2 5 SPVIEW_EXASG 7483 871.891580 + 0.5300E-01 0.001000 10.0 24 F2 1 25 F1 6 SPVIEW_EXASG 7484 871.924283 0.2400E-01 0.001000 10.0 7485 871.955661 + 0.9300E-01 0.001000 10.0 23 F1 1 24 F2 6 SPVIEW_EXASG 7485 871.955661 + 0.9300E-01 0.001000 10.0 23 F2 1 24 F1 6 SPVIEW_EXASG ..................................................................................... Each line has the following structure: +---------------+----------------------------------------------------------------------------------+ | Columns 1+6 | Running index on experimental lines. | +---------------+----------------------------------------------------------------------------------+ | Columns 9+18 | Experimental line wavenumber. | +---------------+----------------------------------------------------------------------------------+ | Column 20 | The plus sign indicates that the line has been assigned and fitted in position. | | | If any other character is placed here, this indicates that the line has been | | | assigned but will not be fitted and will thus not be taken into account by the | | | programs. | +---------------+----------------------------------------------------------------------------------+ | Columns 24+31 | Experimental line intensity. | +---------------+----------------------------------------------------------------------------------+ | Column 33 | The plus sign indicates that the line has been assigned and fitted in intensity. | | | If any other character is placed here, this indicates that the line has been | | | assigned but will not be fitted and will thus not be taken into account by the | | | programs. | +---------------+----------------------------------------------------------------------------------+ | Columns 36+43 | Experimental precision on line position. | +---------------+----------------------------------------------------------------------------------+ | Columns 45+48 | Experimental precision on line intencity (percentage). | +---------------+----------------------------------------------------------------------------------+ | Columns 53+70 | Assignment in the form :math:`J''C''n''` (lower level) :math:`JCn` | | | (upper level). Each experimental line can be assigned to several theoretical | | | transitions if necessary. | +---------------+----------------------------------------------------------------------------------+ | Columns 72+83 | Character chain used to extract desired assignment lines. | +---------------+----------------------------------------------------------------------------------+
