Question about t_i_k_minus_width in C++ Code for Computing Covariance with Range of [-H, +H]

if ((*timestamps_j)[last_l] <= t_i_k_minus_width)

Hello, I had a question about this line of code: t_i_k_minus_width. Should it be changed to t_i_k_minus_half_width instead? My reasoning is that, when computing the integral, we need to examine the range of [-H, +H]. Therefore, we should look for the next t_j_l value that occurs half the width before t_i_k.
