At the previous session, the expert from Poland proposed to clarify the definition of the “on” time for the case of a group of flashes. The expert from GTB pointed out that the GTB Working Group Photometry had recently considered an alternative wording for the same purpose. GRE invited both experts to submit a new proposal to this session.
GRE will also recall that, at its previous session, it had adopted the corrections proposed by GTB (ECE/TRANS/WP.29/GRE/2019/17) but had postponed their submission to WP.29 and AC.1, in order to combine them with the results of the discussion reflected in the previous paragraph.
