Calibrated VLBI data for GRB221009A -- Extreme superluminal expansion traces an ultra-narrow GRB jet across relativistic regimes

Year: 2026

Type: preprint

Abstract: The calibrated data of GRB221009A for the paper "Extreme superluminal expansion traces an ultra-narrow GRBjet across relativistic regimes" submitted to Science. The data are calibrated and produced through the VLBI pipeline (see the linked GitHub repo). ./fits_images/: FITS-format image files for imaging and subsequent analysis with standard astronomical software packages, such as astropy. ./uv_data/: Calibrated $(u,v)$ visibility data for visibility-domain analysis, including model fitting and examination of the visibility distribution, using standard astronomical data-analysis packages such as astropy.
