LLC - Line List Converter
Thibault Merle 2012

This  application  is designed to  convert  linelists from Vienna Atomic 
Line Database  (VALD)  or  Kurucz Atomic Line Database  (KALD)  to  free 
radiative transfer codes format such as MOOG, TURBOSPEC (NOT YET), MULTI.

LLC only needs one argument in input: the  name  of the  ascii file from
VALD or KALD. I/O options are available in config.in file.

Directories
-----------
input: directory where input linelists are stored
output: directory for output linelists
source: directory for fortran90 source code

Files
-----
README: this file
config.in: configuration file of LLC

Compile LLC
-----------
Execute  make  in the source directory.  This will compile the fortran90 
source code and move the application llc in the local directory.  Tested
with gnu, intel and pathscale compilers.

In the directory where is the application, you need to have a configura-
tion file and the input linelist. Currently, you can have  VALD or  KALD
input linelists. Options for output are in the configuration file. 

VALD format
-----------
short format: 

wavelength is given in air
Implemented only for default format
short format can only be used for MOOG output format
long format is required fo MULTI output format (NOT YET WELL TESTED)
Concerning damping parameters:
Stark  and  Waals  are  given  in  logarithm  per  sec and per perturber
at 10000 K.


KALD format
-----------
short format:

vacuum wavelength and air wavelength (2 columns) 
log gf 
Element-Code (e.g., 26.02 for Fe++) 
Lower level: Energy / cm^(-1)  J-Value 
Upper level: Energy / cm^(-1)  J-Value 
damping constants: gamma R, gamma S, gamma W 
   log of radiative damping constant
   log of stark damping constant/electron number
   log of van der Waals damping constant/neutral hydrogen number

Wavelengths MUST be given in vacuum.
E_low and E_up MUST be less than ionization potentiel of the element.
