Computation of the new look-up table with OOF holography and FEM corrections. Each panel shows the expected amplitude φ_⊥C per elevation α with its rms value, δ_rms. The table is based on the gravitational model (shown in Fig. 11) and default FEM look-up table (Fig. D.2). The table is a result of multiple OOF holography observations at several elevations in order to create a reliable gravitational model (Eq. (17)). The contour lines are between –2000 and 2000 µm, with 400 µm intervals. The values determined here correspond well to the observed main-dish deformations by Hoist et al. (2015).
