CCD defect not masked

From Ivan on slack:
I found the cause of this arteficial line in the original sdR-s-b1 files: the CCD defect around pixel coordinates (2271, 870). There is a barely seen bad column that ends this bright spot, which somehow propagated through the reduction.
[@alfredo Mejia-Narvaez] is there a chance to fix it? It looks like a minor issue, but since it coincides with the HeII 4686 line, which is quite important physically, it is worth fixing. Alternatively, it could be masked to exclude it from the DAP analysis

From Oleg on slack:
I think this one should gone with the new pixel masks (not implemented to drp yet). If I identified this region correctly, this bad column is already in the mask, but the mask is not sufficiently extended along the y axis. So, should be easy to fix, just let me provide new pixel masks to Alfredo.
That said, actually, many bad columns end with such a bright spots, and I was hoping that CR rejection works well with them. Apparently not…
