  We present a catalog of solar energetic particle (SEP) events covering solar
cycles 22, 23 and 24. We correlate and integrate three existing catalogs based
on Geostationary Operational Environmental Satellite (GOES) integral proton
flux data. We visually verified and labeled each event in the catalog to
provide a homogenized data set. We have identified a total of 341 SEP events of
which 245 cross the space weather prediction center (SWPC) threshold of a
significant proton event. The metadata consists of physical parameters and
observables concerning the possible source solar eruptions, namely flares and
coronal mass ejections for each event. The sliced time series data of each
event, along with intensity profiles of proton fluxes in several energy bands,
have been made publicly available. This data set enables researchers in machine
learning (ML) and statistical analysis to understand the SEPs and the source
eruption characteristics useful for space weather prediction.
