Duplicate Carina Nebula FP, delisted[edit]

While inspecing our Featured Pictures (FPs), I stumbled over the funny fact that we have two almost identical FPs of the central region of the Carina Nebula: Eta Carinae Nebula 1.jpg, nominated in 2007, and NGC 3372a-full.jpg, nominated in 2018, are more or less the same.

What has happened here? The first file, Eta Carinae Nebula 1.jpg, was originally much smaller; only in 2009 a user uploaded the full resolution photo over the previous version. And, more important, in 2014‎ Eta Carinae Nebula 1.jpg was nominated for deletion. In 2021 it was undeleted again (reasoning), but while it has been deleted, NGC 3372a-full.jpg was uploaded, nominated and promoted.

When I compare both photos on the pixel level, I see that NGC 3372a-full.jpg has a little bit more contrast. It should also be the better file, technically speaking, because it uses lower compression (and therefore is very large: 200 MB vs. the 91.25 MB of Eta Carinae Nebula 1.jpg), but to be honest it is hard to see any sharpness difference. There is, of course, a difference in the metadata: NGC 3372a-full.jpg contains more metadata tags, while Eta Carinae Nebula 1.jpg is missing almost all metadata.

What should we do now? Cart, to whom I wrote first about this issue, and me think that one of the two FPs should be delisted because (besides the difference in contrast) the photos are really identical. (NB: We do not want to delete any of both files, but only one of them should be a FP.) For clarity and transparency, I have created this unusual delist nomination so that you can decide which of the two files you want to keep as FP and which one should be delisted. Please vote with {{Keep}} under the version you want to keep as FP and/or with {{Delist}} under the version you want to delist. Thank you very much! --Aristeas (talk) 08:49, 7 October 2023 (UTC)[reply]

  •  Comment Yes, but nevertheless it’s much clearer when people vote with {{Keep}}, isn’t it? Both pictures are already FPs, so we need to be explict which one should be kept. --Aristeas (talk) 11:09, 7 October 2023 (UTC)[reply]
  • And if you are angry about this nomination, Yann, because File:NGC 3372a-full.jpg was nominated by you, then I am sorry. I did not want to upset you, I just wanted to handle this as transparently as possible. So please do not take this personally. Note that I voted to keep the version which was nominated by you. But if you prefer I can stop this nomination, then you can handle this issue the way you want. --Aristeas (talk) 11:14, 7 October 2023 (UTC)[reply]
  • OK, but what do we need to change? The headline says “(delist)”, the filepath says “removal”, I have changed my vote to {{Delist}}, so this is a delisting nomination, it is just not clear yet for what file. In the end this is a special nomination which cannot conform completely to the usual form of delist nominations, just because we are handling a special case. It’s clear that we will have to handle it manually in the end, FPCBot will not be able to do that. --Aristeas (talk) 11:22, 7 October 2023 (UTC)[reply]
  •  Comment To be clear: This is not about Aristeas’s personal preferences about an image, only a way to decide which FP to keep. During the big, and long overdue, cleanup of the FP system that Aristeas (mostly) and I have done during the past month a lot of discrepancies and errors were found. This included filing mistakes, faulty categories, fake FPs, lost FPs, vandalism, and deceptive ways to manipulate the FP system. It was during this cleanup that these two files that have accidentally both become FPs were found.
Most of the errors could be corrected in a pretty straightforward way, but this “blooper” needs the attention of the FP community. This is the first time (AFAIK) that we’ve had this situation, therefore no exact nomination template for this exists, Yann.
The ‘Delist’ system was the closest we could find. So please ignore the inexact wording on this nom, bear with this exceptional situation, and simply vote for which one of the versions you like to keep as FP and which one should be delisted. Thank You! --Cart (talk) 12:22, 7 October 2023 (UTC)[reply]
