+
+The `ScreenP` parameter group contains parameters for describing a 2-dimensional diagnostic screen used to measure the transverse distribution of a particle beam.
+The components of this group and their defaults are:
+```{code} yaml
+ScreenP:
+  resolution_x: 0  # [int] Number of screen pixels in the horizontal direction.
+  resolution_y: 0  # [int] Number of screen pixels in the vertical direction.
