Top left: LASCO C3 image (same as Figure 5) with the prominent coronal streamers, S1 and S2, marked. Top right: solar-eclipse image (same as Figure 1) with the LASCO image superimposed and aligned in both coordinate system and scale. Middle and bottom: radial brightness profiles of the F-corona in each color channel, measured along the streamer and opposite directions. The middle panels correspond to the S1 streamer, whereas the bottom panels correspond to the S2 streamer.
