Discrepancy in channel dimension of sample data (25 vs. expected 23?) #14

Hi authors,

Thank you for releasing the GigaTIME dataset and code. It's a fantastic resource for our research.

I am currently exploring the sample test data provided in the repository (data/sample_test_data/data/0_556_556_556_comet.npy) and noticed a potential discrepancy regarding the channel dimension that I hoped you could clarify.

In the documentation (or based on my understanding of the model architecture), I was expecting the channel dimension to be 23 (representing the comet kernels/templates). However, the actual data has 25 channels.

Could you please clarify:
Is the expected channel count actually 25?

If the count should be 23, what do the extra 2 channels represent? (e.g., Are they background estimates, masks, or padding?)

Is there a specific preprocessing step required to slice these down to 23, or is this an updated version of the dataset?

Thanks again for your work!

Best regards,

Zhe Yin
