MSL Navcam mosaic. The mosaic as shown above covers a total field of approximately ${90}^{\circ }\times {70}^{\circ }$, and required portions of 6 individual Navcam images ($\sim 2.75$ images wide by $\sim 1.75$ images high) to cover the field. The Perseverance Navcams will cover the same field of view in a single image. Reducing the image-to-image overlap in a mosaic improves the quality of a mosaic by reducing the number of seams. The reduction in overlap also reduces downlinked data volume by eliminating the redundant data in the overlap regions
