Update Readme

         takes the fits files provided by the data reduction software (DRS) of 

         HARPS or HARPS-N as an input. 

         An example for the input files and the corresponding output file is 

         provided in the directory /input with the sole purpose of allowing to test 

         the proper compilation and running of the procedure. Details on an auxiliary 

         source file (mpfit.pro) required for compilation are provided in the 

         header of the procedure file and in Appendix A of the above mentioned 

         paper. Interested users are warmly recommended to read them before 

         compiling and running the procedure.

File summary and contents:

- asym_ind.pro: the IDL procedure to compute the asymmetry indicators and the 

  FWHM of the CCF as specified by Lanza et al. 2018; please change the string 

  PATH and the string OPERATION before compiling and running as explained in the

  header of the procedure file (see also Appendix A of Lanza et al. 2018); when 

  using files produced by the DRS of HARPS@ESO, please check the dimensions of the 

  matrixes extracted from the FITS files because the current version of the 

  procedure assumes those of the files produced by the DRS of HARPS-N@TNG;
