A computer code (procedure) written in Interactive Data Language (IDL)
to compute the spectral line profile indicators used in the above
research article starting from the fits files provided by the data
reduction software (DRS) of HARPS or HARPS-N. The procedure takes the
cross-correlation function (CCF) files provided by the DRS as an input.
A computer code (procedure) written in Interactive Data Language
(IDL, version 8.4) to compute the spectral line profile indicators used
by Lanza et al. (2018, A&A in press, arXiv:1804.07039). The procedure
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
article. Interested users are warmly recommended to read them before
paper. Interested users are warmly recommended to read them before
compiling and running the procedure.
File summary and contents:
- README.md: this description ASCII file;
- 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);
- mpfit.pro: the fitting routine used by asymmetry_indicators_v1.0.pro (see the header of the above file for instructions about the compilation and Lanza et al. 2018, Appendix A); this procedure is authored by Craig B. Markwardt, NASA/GSFC; see
- 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;
- mpfit.pro: the fitting routine used by asym_ind.pro (see the header of the
above file for instructions about the compilation and Lanza et al. 2018,
Appendix A); this procedure is authored by Craig B. Markwardt, NASA/GSFC; see
- input: a directory containing a sample dataset consisting of *_ccf_* and *_bis_* files of the star HD108874 as provided by the DRS of HARPS-N (see Lanza et al. 2018, Appendix A); for more information on this dataset you can refer to our paper dedicated to HD 108874, that is Benatti et al. 2017, A&A 599, A90;
- output.dat: the sample output file containing the asymmetry parameters and the FWHM of the CCF together with other information as specified in the header of asymmetry_indicators_v1.0.pro;
- ms31010corr.pdf: the preprint of the paper Lanza et al. 2018, accepted to A&A.
