@brief This procedure measures the raw XY positions and widths
of Th-Ar lines on an ThAr arc echelle exposure.
It computes the differences with the predicted positions
@param raw_image The input raw frame (splitted)
@param raw_header An array containing the input image headers.
The ordering must be the same as the ordering
of images in the input image list
@param recipe_id name of calling recipe
@param parameters The recipe parameter list
@param mod_tbl Input model table from uves_physmod_create_table()
@param l_tbl Temporary table
@param m_tbl Temporary table
@param p_tbl Temporary table
@param rline_tbl Temporary table with predicted line positions
@param mline_tbl Temporary table with corrected predicted line positions
@param npline_tbl Temporary table
@return 0 if everything is ok, -1 otherwise
This function creates tables rline_tbl containing predicted positions
(XMOD,YMOD) and the differences, fits with a polynomial of degree 2,2
on X,Ythis difference depending on the positions (X,Y), computes
the projection map with a polynomial fit of degree 2,2 on X,Y and save
them in the table npline_tbl.
