CaloArt -- Generated samples for CaloChallenge Datasets 2 and 3

This dataset contains generated calorimeter shower samples and correspondinghigh-level features produced with CaloArt for CaloChallenge Dataset 2 (CCD2)and Dataset 3 (CCD3). The files samples_ds2.hdf5 and samples_ds3.hdf5 contain the generated showersamples used for the CaloArt evaluation on CCD2 and CCD3, respectively. Thefiles CaloChallenge_ds2_hlfs.zip and CaloChallenge_ds3_hlfs.zip contain thecorresponding high-level features used for physics-observable comparisons andmetric evaluation. CaloArt is a DiT-style transformer model for direct raw-voxel calorimetershower generation. It uses large 3D patch tokenization and studies predictiontarget choices within a conditional flow matching framework. The releasedsamples correspond to the final CaloArt configurations reported in theassociated paper. Files included:- samples_ds2.hdf5: generated CaloArt samples for CaloChallenge Dataset 2.- samples_ds3.hdf5: generated CaloArt samples for CaloChallenge Dataset 3.- CaloChallenge_ds2_hlfs.zip: high-level features for the CCD2 generated samples.- CaloChallenge_ds3_hlfs.zip: high-level features for the CCD3 generated samples. The samples and high-level features are intended to support reproducibility ofthe reported CaloArt evaluation and to facilitate comparison with other fastcalorimeter simulation methods.
