| strip | A strip is a scan along a line of constant survey latitude eta . The center of a stripe is set at a given eta; centers of strips have a boresight offset added. Because the columns of CCDs have gaps between them, it is necessary to take two offset but overlapping observations to fill in a stripe. These two scans are called strips. Note that while strips are centered on a given eta, THEY ARE NOT BOUND BY ETA LINES. Thus they are rectangular regions. and can overlap at the poles.
