Does the sensitivity calculator account for shadowing?

Yes, the ALMA Sensitivity Calculator takes into account the shadowing by reducing the effective antenna surface area by a factor related to the target declination. As the Sensitivity Calculator always assumes that the target is observed at transit, the shadowing estimate will in general be a lower limit.
