Cyan = FoV of 15 arcmin, blue = 10, green = 5, orange = 2, red = 1.
Type of AO = GLAO, ZD = 0 deg, λ = IC (K).

The distance from the centre of the field of view is given in units of the field's size.

The solid dots refer to positions along the field-of-view's positive x-axis, while the open squares denote positions along a line that is inclined by 36° with respect to the x-axis. In the simulations the LGS were distributed in a ring around the field of view at 72° intervals, with one LGS lying on the positive x-axis. Hence, stepping along the solid dots one moves from the field's centre towards an LGS, whereas stepping along the open squares one moves from the centre outwards along a line bisecting two LGS. Note that this makes an appreciable difference for large field sizes.
