DESCRIPTION:Speakers: Luca Malavolta (Dipartimento di Fisica e Astronomia 
 - Università degli Studi di Padova)\nHigh-resolution transmission spectro
 scopy is one of the most fruitful techniques to infer the main opacity sou
 rces\, thermospheric temperature and evaporation processes in the atmosphe
 re of transiting exoplanets. Before retrieving the planetary features\, ho
 wever\, observed spectra must be corrected for sky emission\, residual atm
 ospheric dispersion\, presence of telluric features and interstellar lines
 \, center to limb variation\, and Rossiter-McLaughlin effect\, with each o
 f these steps possibly introducing systematic errors and altering the fina
 l transmission spectrum. The current lack of a public tool able to automat
 ically extract a high-resolution transmission spectrum creates a problem o
 f reproducibility of scientific results. As a consequence\, it is very dif
 ficult to compare the results obtained by different research groups and to
  do a homogeneous characterization of the properties of exoplanetary atmos
 pheres. In this talk I will present a standard\, publicly available\, user
 -friendly tool\, named SLOPpy (Spectral Lines Of Planets with python\, Sic
 ilia et al. submitted)\, that automatically extracts the optical transmiss
 ion spectrum of exoplanets and allows the perfect reproducibility of resul
 ts. To validate the code and assess its performance\, we performed a compa
 rison with literature results of ideal targets for atmospheric characteriz
 ation observed with HARPS and HARPS-N\, finding a good agreement with publ
 ished results. I will conclude the talk by highlighting a series of best p
 ractices that can greatly improve the reproducibility of results even when
  the analysis tools are not publicly released.\n\nhttps://meetings.aip.de/
