Distributions of CCF(v, t) values obtained using the Fe I model template and by combining the datasets from nights 1 and 2. The filled blue and black outlined distributions are the out-of-trail values and the in-trail values, respectively. The Welch’s t − test rejects the null hypothesis (i.e., that the two samples are drawn from equal-means samples) at a 10σ significance.
