description: Summary

This data repository is associated with the work presented in paper "ExoMiner++ 2.0: Vetting TESS Full-Frame Image Transit Signals".

Contents



exominer_new_architecture.png: image of the new ExoMiner model architecture. Includes details on the dimension of the inputs and feature maps at each stage of the architecture.

exominer_new_architecture_high_level.png: high-level depiction of the new ExoMiner model architecture as shown in the paper.

exominer_new_model_detailed.png: shows detailed information on the model architecture, including the size of the inputs and outputs to every layer.

ExoMiner model: a compressed file containing the TensorFlow Keras model used in this experiment for vetting TCEs.

exominer_plusplus_new_ensemble-models_cv.tar.gz: compressed file containing the average ensemble models from the 5-fold cross-validation experiment for the new ExoMiner architecture.

cv_tfrecords_tess-spoc-tces_2min-s1-s94_ffi-s36-s72-s56s69_10-30-2025_1406-eval.tar.zst: a compressed file of the TESS dataset (including both SPOC FFI and 2-min TCEs) used to run the cross-validation experiments in the paper. The examples are split across multiple files (aka shards) in TFRecord format. The features are unnormalized (at least the ones that require normalization using training set statistics). You can use this dataset to compute normalization statistics based on a training set of your choosing, and then normalize the features accordingly. This dataset does not include the unlabeled examples (aka UNK TCEs).

cv_tfrecords_tess-spoc-tces_2min-s1-s94_ffi-s36-s72-s56s69_10-30-2025_1406-eval-shard_tables.zip: this compressed zip file contains the cross-validation fold tables used in this work. These CSV files describe the content of each cross-validation fold in terms of its TCE examples. Each CV fold table filename follows pattern labeled_dataset_tbl_fold{cv fold number}.csv. There is also a CSV file name "folds_statistics.csv" that contains the distribution per subclass for each CV fold, including percentages. Description of columns in the CV fold tables is found in the table below.





Column
Description


example_i_tfrec (int)
Position of the example (i.e., TCE) in the TFRecord file (sequential access)


shard (str)
TFRecord filename to which the example belongs to


uid (str)
TCE ID following pattern {tic_id}-{spoc_tce_planet_number}-S{sector_run}. Not unique since there are TCEs from both 2-min and FFI data


target_id (int)
TIC ID


tce_plnt_num (int)
TCE planet number from the SPOC pipeline


sector_run (str)
SPOC sector run ID. For single-sector runs, just a single digit; for multi-sector runs, {start_sector}-{end_sector}


label (str)
Subclass (i.e., disposition) of the TCE. One from KP (known planet), CP (confirmed planet), FP (TFOPWG false positive TOI), EB (Prsa's EB), BD (TFOPWG SG1 brown dwarf),  and NTP (non-transiting phenomena based on TEC's results)


obs_type (str)
'2min' if TCE comes from 2-min SPOC planet searches; ffi if it comes from FFI SPOC planet searches


uid_obs_type (str)
TCE unique ID that ads to uid the observation type separated by an underscore






cv_tfrecords_tess-spoc-tces_2min-s1-s94_ffi-s36-s72-s56s69_10-30-2025_1406-predict.tar.zst: a compressed file of the TESS dataset including both UNK SPOC FFI and 2-min TCEs. This is the unlabeled dataset that was used for vetting.

tfrecord_feature_schema.txt: describes the features stored for each example (i.e., TCE) inside the TFRecord files.

vetting-catalog_FFI.csv: CSV file that contains the vetting catalog using the new ExoMiner model for TESS SPOC FFI unlabeled TCEs. Description of columns in this catalog are found in the table below.
