\subsection{Background estimation}  \label{sec:bg_calc}  The first step of smFRET analysis involves estimating the background level. For example, to compute the background every 30s, using a minimal timestamp delay  threshold of 2 ms for all the photon streams we execute: \begin{verbatim}  d.calc_bg(bg.exp_fit, time_s=30, tail_min_us=2000)
