The dual-frequency calibration of ionosphere influence in VLBA data processing

Abstract

Some results of processing data of Very Long Baseline Array (VLBA) experiments titled RDV14, RDV15, RDV16, and RDV17 are presented. Observations had been carried out on 15/04/1999, 10/05/1999, 21/06/1999, and 02/08/1999. The Flexible Image Transport System (FITS) files have been created with a VLBA correlator and then placed into archive. Later, these data have been kindly placed at my disposal by Dr. Leonid Petrov (Goddard Space Centre). The software project titled “Astro Space Locator” (ASL for Windows) has been used for post-correlation data processing.

Acknowledgements

I would like to thank Dr. Leonid Petrov from the Goddard Space Centre for data of four VLBA experiments that were kindly placed at my disposal. I also thank my colleagues from the Astro Space Centre, Sergey Likhachev and Igor Guirin for their assistance during data processing and very useful discussions.
