Bug Report: Inconsistency in Nearest Source Estimation in `dc_mag` Calculation #44

Open MohamadJ283 opened 5 months ago

MohamadJ283 commented 5 months ago

Hey,

During our work on anomaly detection(cc: Mr. @ManuGangler), we've identified a discrepancy in the calculation of dc_mag.

Nearest Source Estimation Error: Upon further investigation, we've observed an inconsistency in the nearest source estimation process across filters (red/green) for the same object. Contrary to expectation, in certain cases, we've found that the nearest source varies between filters. This discrepancy arises from instances where noise detection is erroneously classified as a source in one filter but not in the other.

The issue is in: photometry_tutorial.ipynb (refer to [In [6]] section).

Please check this notebook; we explained in detail the error and suggested a modification.

Best regards,

Thanks @MohamadJ283 for reporting! However I cannot access the notebook. Is this in a private repository?
