Radio Galaxy Zoo Data Release 1

We present the first data release of Radio Galaxy Zoo, an online citizen science project that  enlists the help of citizen scientists to cross-match extended radio sources from the Faint Images of the Radio Sky at Twenty Centimeters (FIRST) and the Australia Telescope Large Area Survey (ATLAS) surveys, often with complex structure, to host galaxies in $3.6\,\mu$m infrared images from the {\em{Wide-field Infrared Survey Explorer}} (WISE) and the {\em{Spitzer Space Telescope}}.  This first data release consists of 100,185 classifications for 98,559 radio sources from the FIRST survey and 582 radio sources from the ATLAS survey.  As such, there are radio sources for which more than one classification is listed.  We include two tables for each of the FIRST and ATLAS surveys: 1) the identification of all components making up each radio source; and 2) the cross-matched host galaxies.  These classifications have an average reliability of 0.83 based on the weighted consensus levels of our citizen scientists. Please refer to the RGZ Data Release 1 paper by Wong et al 2024 for more details.
