New version as of 2025-10-26. Changes Only format corrections and deletion of duplicate entry (WIDE85_3) Context and methodology The dataset  belongs to publication: Axel Nothnagel (2009) Conventions on thermal expansion modelling of radio telescopes for geodetic and astrometric VLBI; Journal of Geodesy, Vol. 83(3), 787-792, DOI: 10.1007/s00190-008-0284-z, where the general concept of thermal expansion modeling is described. The data was collected from on-site personnel who measured the dimensions of the structural parts or extracted them from construction drawings. Technical details The data is stored in fixed format ASCII, with the data of each telescope in a single line. The format is described in the header of the file.  No special software is needed to read and use the data.
