# tool si.read.audience_map

a brand, two facets or a facet and a community, the window: the shared subjects, the share, the lift, the negative control that bounds it, and the size as bounds.

[figure: Over MCP, si.read.audience_map takes AudienceMapInput and returns a card whose body is AudienceMapCell.]

the shared subjects, the share, the lift, the negative control that bounds it, and the size as bounds. The call needs the read grant at the brand rung.
