@brief This procedure makes the order definitions and wavelength
calibration from the wavelength projection map, and saves the
data in tables and global keywords in echelle context.
It generates order and line tables.
@param raw_header header of raw frame
@param chip UVES chip ID
@param recipe_id name of calling recipe
@param parameters input recipe parameters
@param npline_tbl input table
@param ord_tbl output order table
@param lin_tbl output line table
@param w_tbl output table with results from regression
@param s_tbl output table with results from regression (same as w one?)
@param abs_ord_min min absolute order
@param abs_ord_max max absolute order
@param poly2d output polynomial with coefficients from regression:
Order=poly2d(X,YNEW) fit is stored in column RORD
@Note: this has been ported from UVES MIDAS pipeline
