The challenge is the predict the center of each dark matter halo in the provided 120 test skies. Each test sky can have either 1, 2, or 3 dark matter halos. x- and y-coordinate values are in terms of pixels.
Each row of the submission file must have 7 columns in comma separated values (CSV) format:
SkyId, x_halo1, y_halo1, x_halo2, y_halo2, x_halo3, y_halo3
If the sky for which you are making a prediction has fewer then 3 halos, simply use 0.0, 0.0 as the prediction. For example, for 2 halos:
Sky73, 482.59, 1294.5, 2430.3, 894.7, 0.0, 0.0
