1.1.2 Source regions of the slow solar wind

N-S mosaic

~50 hrs + slews for mosaic of 12 positions

• RSwindow - Earth facing for additional observation from Sun-Earth aligned instruments

• Mosaic to map half of the Sun

The sequencing of the mosaic is changed to match the rastering pattern of Hinode/EIS
