Correction for pointing errors of Siberian Radioheliograph antennas

Solar-Terrestrial Physics
For radio interferometers, antenna pointing accuracy is critical, as deviations in the direction of the beam from the source not only reduce the signal level, but also lead to incorrect measurements of visibility phases.

PHASE ERROR MEASUREMENT AND CORRECTION IN 8-CM RADIOHELIOGRAPH [PDF]

1977-01A computer program to improve dirty solar maps on the basis of measured phase errors was developed for the 8-cm radioheliograph at Toyokawa. The radioheliograph is a simple T-shaped phase-switching interferometer, and is not equipped with a phase ...

Three-minute oscillations above sunspot umbra observed with the Solar Dynamics Observatory/Atmospheric Imaging Assembly and Nobeyama Radioheliograph

, 2012
Three-minute oscillations over a sunspot's umbra in AR 11131 were observed simultaneously in UV/EUV emission by the Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA) and in radio emission by the Nobeyama Radioheliograph (NoRH).

Phase calibration scheme for a "T” array

, 1999
A calibration scheme based on closure and redundancy techniques is described for correcting the phase errors in the complex visibilities observed with a T-shaped radio interferometer array. Practical details of the scheme are illustrated with reference

Radio Signature of Higher Atmospheric Meridional Flow and Implications for Magnetic Trees in the Sun

The Astrophysical Journal
The coupling between plasma flows and magnetic fields in the solar atmosphere governs the transport of angular momentum and the redistribution of magnetic flux, yet its manifestation in the magnetically dominated upper chromosphere remains uncertain ...
