Description
Context
This file contains gravitational deformation information for various radio telescopes used for geodetic and astrometric VLBI. It is the extra delay introduced by deformation of the antenna.
Methodology
- The data was collected from on-site personnel and during campaings described in the related publications
- Involved persons are listed as "Contributors"
- All related publications are listed under "Related work"
Technical details
- The data is stored in GravDEx (GRAVitational Deformation EXchange) file format described in Lösler et al. (2026)
Changes relative to previous version
This version 1.0 differs from the previous one (version 2025.09.28, doi: 10.48436/pc0ge-sh436) solely in respect of the delay values for HOBART26, which are dependent on the azimuth for the first time.
