Competing Interests

Dr P. Légeron, currently scientific director of Stimulus, provided the data and read the final draft of the article to check for unintended errors, but did not otherwise contribute to the article. The other coauthors and the two laboratories of the CNAM (MESuRS and CEDRIC) received no support or funding for this work. This does not alter the authors' adherence to PLOS ONE policies on sharing data and materials.
