Results of PCA-NEGFC (baseline) on the training set

The images below show the baseline results on the sphere0 training data set:

Left: Residual map obtained after a PCA subtraction using 10 principal components to build the reference. The two injections, 'planet b' and 'planet c', are highlighted in orange and green. Right: Corresponding 5-sigma detection limits for every spectral channel of SPHERE-IFS and its median (thick line).

Left: Results in terms of astrometry retrieval using PCA-NEGFC. The position of each point shows the relative position with respect to the ground truth (standing in the middle) with its 1-sigma uncertainty (shaded area). Middle and Right: Results in terms of spectro-photometry estimation using PCA-NEGFC. The top panel shows the extracted spectrum and its corresponding 3-sigma uncertainties. The bottom panel shows the residuals wrt the ground-truth with the 3-sigma uncertainties (shaded area).

Current results of the Phase 2 (leaderboard)

The table below shows the current algorithms submitted on the EvalAI platform, with the corresponding distance, used as a metric for comparison.

Publication of the metrics used for the Phase 2

After setting the second phase of the Exoplanet Imaging Data Challenge, we gathered the description of the second phase, the challenge design, the data set available and metrics used to make the comparison in an SPIE conference proceeding. This proceeding is the result of an oral contribution presented at SPIE Astronomical Telescope + Instrumentation taking place from the 17h to the 22th of July 2022 in Montréal (Canada).

All members of the Exoplanet Imaging Data Challenge Phase 2 working group are co-authors.

Publication of the comparison of the Phase 2

After the deadline set on 31/05/2024, we compiled the results and published the comparision in an SPIE conference proceeding is the result of an invited oral contribution presented at SPIE Astronomical Telescope + Instrumentation taking place from the 16th to the 21st of June 2024 in Yokohama (Japan).
