PRECL: A new method for interferometry imaging from closure phase

Understand

For short-wavelength VLBI observations, it is difficult to measure the phase of the visibility function accurately.

• The closure phases are reliable measurements under this situation, though it is not sufficient to retrieve all of the phase information.
• We propose a new method, Phase Retrieval from Closure Phase (PRECL).
• PRECL estimates all the visibility phases only from the closure phases.
