Top: Electron density maps derived from Metis pB data in the two regions surrounding the east and west equatorial streamers, centered, respectively, at PA = 90° (left) and at PA = 292.5° (right). The thin vertical lines mark the regions considered in the study. Bottom: Electron density radial profiles obtained from this analysis, compared with the streamer profile obtained from Metis first-light data (green by Romoli et al. 2021) and with other density profiles for equatorial and mid-latitude streamers reported in the literature, as is indicated in the legend (see also the text).
