Output files

20150526 incomplete / outdated: being updated

At the end of the processing of each star, MyGIsFOS produces an extensive output describing the results in detail and allowing to follow the various steps of the analysis. The entire output is contained into a directory named STAR_name-of-the-star. If the directory exists already, all it's content is backed up within the new version of the output directory, in a subdirectory called backup_timestamp_of_the_new_run (e.g., you run on 15/10/2014 a star called 13p14 that had been run before, MyGIsFOS create a new STAR_13p14 and back up the old one as STAR_13p14/backup_20141015113531).

Within the STAR_ folder, MyGIsFOS writes a number of output files, all but one in ASCII format. All the ASCII files begin with a timestamp (as the one in the backup directory above) listing (yyyymmddhhmmss) the time of the beginning of the run. This means that all the stars processed together will have the same timestamp, even if the run lasted hours. This allows to always track back in which run a file has been generated.

A description of the various output files follows (please notice some long lines might be wrapped in the Evernote online format):

abundances.out

This file resumes the main results of the analysis, namely the final atmospheric parameters and the averaged abundances of all the measured ions.

In the parameters line, the last number is a flag indicating if the star has run past the max number of loops (i.e., has failed to converge). 0 means convergence has been achieved. For [X/Fe] ratios, if Fe II has been measured, [X/FeII] is given for ionized species and [X/FeI] for neutral species. If only Fe I has been measured, it is used for all the species.
