8.3 Options

For LINE1 most of the options described in Sect. 5.4 and 5.5 are valid. There are some further options. Their meaning should be clear ...

MISSING OCCUPATION NUMBERS FROM I MODELS
The occupation numbers of newly considered levels are read from I models (I = max i, see ABUNDi and MODINi, above) in increasing order.

ITERATION |~| IN |~| DEPTHS ii jj kk
The the first kk iterations are carried out only between depth points ii - jj.

MATRIX |~| INVERSION: |~| MINV
The matrix inversion for the solution of the statistical equations is carried out by the SCILIB routine MINV. Attention: numerically instable for n > 200,..., 220.

MATRIX |~| INVERSION: |~| INV
The matrix inversion is done by an own routine.

MATRIX |~| INVERSION: |~| GIRL
The matrix inversion is done by routine GIRL (single precision). More stable than MINV in some cases!

MATRIX |~| INVERSION: |~| GIRLDP
The matrix inversion is done by routine GIRL (double precision).

MATRIX |~| INVERSION: |~| SGETRF |~| + |~| SGETRI
The matrix inversion is done by the LAPACK routines SGETRF and SGETRI.

USE |~| DIMITRIJEVIC |~| BROADENING |~| TABLES |~| FOR |~| C |~| IV
With this option, all C IV line transitions in the atomic data file ATOMS are calculated with the stark broadening tables by Dimitrijévic (if found there).

If the Dimitrijévic tables shall be used only for selected lines, in ATOMS formula 5 instead of formula 3 or 4 has to be requested.(Sect. 3).
-- The tables (Sect. 8.1) have to be loaded in any case ... --

USE |~| DIMITRIJEVIC |~| BROADENING |~| TABLES |~| FOR |~| C |~| V
like USE |~| DIMITRIJEVIC |~| BROADENING |~| TABLES |~| FOR |~| C |~| IV

CPU-TIME |~| TTTTT

maximum CPU time for the job, TTTTT given in seconds
CPU-TIME |~| 0.0
This card transfers the total cpu time (then: stop) to LINE1. There are load dependent variations of the system cpu time which accounts to the user cpu time. These variations can effect the security time needed by LINE1 in order to complete the iteration, write the model, etc.

ACCEPT |~| CHANGED |~| EFFECTIVE |~| TEMPERATURE |~| X
LINE1 generally takes Tefffrom the start model (MODIN). For very large models the change of Teff (in small steps) takes much less times than the complete new calculation with mainly the same (!) parameters. However, still some iterations are needed ...

ACCEPT |~| CHANGED |~| ABUNDANCES
LINE1 generally takes the chemical composition from the start model (MODIN) and ignores ABUNDANCE cards in them input file but for newly implemented elements. For very large models the change of the abundances (in small steps) takes much less times than the complete new calculation with mainly the same (!) parameters. However, also still some iterations are needed ...

DOPPLER |~| PROFILES
This option sets the line broadening of all line transitions in the atomic data file ATOMS generally to Doppler line broadening. This can be used for a quick overview about blends within a selected range.

FORCE USE OF LINE BROADENING TABLES
This option enables the use of line broadening tables instead of approximate formulae during the model atmosphere calculation.

like USE |~| DIMITRIJEVIC |~| BROADENING |~| TABLES |~| FOR |~| C |~| IV

LINEARIZATION |~| MODE: |~| BLOCK-MATRIX |~| ITERATION, |~| ION
analogously to LINERIZATION |~| MODE ... in Sect. 5.4. This card allows to select one single ion to iterate.

LINE |~| TEMPERATURE |~| FROM |~| FORMATION |~| DEPTH
The line temperature T_line is by defaults set to 3
4 ^. Teff (Sect. 3). The different lines form in very different depths, i.e. at different temperatures. This card allows to select the temperature at the formation depth ( = 1) of the line core for every lines as line temperature, respectively.

MIKROTURBULENCE |~| [KM/SEC] |~| 0.0
analogously to Sect. 5.4. LINE1 considers the microturbulence also in the calculation of the line profiles.

PRINT |~| EQUIVALENT |~| WIDTH
A small table with the equivalent widths of all selected lines is printed to STDOUT.
Attention: For the calculation of the equivalent widths of the selected lines, the interval [CONT RED,CONT BLUE] (Sect. 3) is used -- with all included blends
In order to study the equivalent widths of selected lines in detail the blendrange has to be set to a small-enough value that includes only the components of the multiplet or the atomic data file ATOMS has to be created with only the requested line transition.

PRINT |~| EQUIVALENT |~| WIDTH |~| (LONG)
like PRINT |~| EQUIVALENT |~| WIDTH but this table includes all frequency points in the interval [CONT RED,CONT BLUE] and gives additionally the accumulated equivalent widths.
