A new paper has been submitted to ArXiv: Independent Recovery of Vanishing Sources on POSS-I Photographic Plates Using Automated Source Detection and Cross-Epoch Matching by Zachary Hayes Source: https://arxiv.org/abs/2604.04810 PDF attached. I...

Something deep within me i suspects that Big UFO promoters will be late adopters of this system!

Your periodic reminder that Loeb's Galileo Project involves putting him in charge of a billion-dollar budget and giving him the authority to commandeer any or all of the world's telescopes on a whim if he thinks something alien might be passing by.

Oooh, thanks for that! I became familiar with the terms in a job in the mid 90s, and I suspected that they weren't invented in order to help identify whether the bourbon biscuits were broken before being put in the packs, or whether the bottle of...

Thanks - I was implicitly referring to this scheme as well: the D‑C‑R‑I scheme (Detection, Classification, Recognition, Identification). This appears to be the quasi‑official version used by the DoD / US Army since 2005. It is definitely worth...

If that's your choice, can you please take into consideration the ~7% of males who simply cannot detect any difference between such yellows and greens.

I got some of the code running and experimented with visualizing the filtering. What the pipeline is doing is finding all the blobs of light in the planes, and then rejecting ones that are known stars or that don't look like points of light...

search_radius_arcmin: float = 90.0 - yes, that's in the code. But: - It is not used as the spike cutoff - It is not the distance used in the rejection rule Spike rejection is governed by arcsecond‑scale rules. Arcminute radii only decide which...

Jeebus, 5pm? Someone had it livestreamed on their phone in the pub last night, and by my recollection it was past 3am. (No need to recollect, one of my IRC windows says "03:09 < FatPhil> splashdown!".) Trust me, we euros enjoyed the event more...

I have now downloaded and processed 30% of POSS-I plates using Vasco60 pipeline. I decided to build a script to understand the differences between my and MNRAS 2022 final survivor set R. (5,399 rows in MNRAS 2022). Findings were surprising so I...

It seems to be a query around the tile center, not stars. Vasco60 use the 90' as you have a default search_radius_arcmin: float = 90.0 in class SpikeConfig: and cli_pipeline.py:610 does not override it to 1.5
