Table 2

Properties of the OOF holography observations.

Name	Freq. GHz	Maps size arcsec²	Scan speed arcsec s⁻¹	d_z cm	φ_⊥ µm
9 mm	32.00	360 × 360	40.0	±2.2	745
7 mm	34.75	340 × 340	22.8	± 1.9	686

Notes. Given are the receiver name, central frequency, maps size, scan speed, amount of defocus for the OOF holography maps, and the obtainable resolution for φ = 1 rad of phase-error.
