Computation of the Output Absorption Spectrum

This is the main step achieved by the command:


\fbox{\tt COMPUTE/ABS \ \ SYNEMI \ \ SYNABS \ \ ABSC \ \ ABSP \ \ NAMEP}



SYNEMI 		 : 		 input emission spectrum 
SYNABS : output spectrum with synthetic absorption lines
ABSC : table containing the cloud model
ABSP : table containing the atomic data
NAMEP : image containing the instrumental response
Warning : this image must have the same step size as SYNEMI

Then the program:

1.
Types:


PSF: FWHM a ANGSTROM
STEP: b
Where a and b are read from the description of the PSF; only as a check for the user.

2.
Computes:


The synthetic spectra according to the parameters of table ABSC.
The output spectra are:

\begin{displaymath}\left\{ \begin{array}{ll}
SYNABS1 & \mbox {if option Voigtia...
...S0 & \mbox {if option Maxwellian profiles}
\end{array} \right. \end{displaymath}

and

\begin{displaymath}\left\{ \begin{array}{ll}
SYNABS1C & \mbox {convolution of \ above spectra}\\
or & \\
SYNABS0C
\end{array} \right. \end{displaymath}
