Comparison between white-light pB synoptic maps and streamers extracted from simulations for models without (top row) and with (bottom row) the far-side AR. The background is a synoptic map made using LASCO/C2 white-light brightness images over the corresponding Carrington rotation (CR2240). With the chosen color scale, the SB appears as dark regions. The HCS extracted from simulations is shown as a blue line. The pseudo-streamers extracted from simulations are shown as reddish regions. The longitude of the far-side AR on February 15, 2021, is shown with a vertical red line. We keep the same nomenclature as in Fig. 3 for the identification of streamers and pseudo-streamers.
