Miserable Failures

Straightforward Failures

This image is from the Moon; but it fails for lack of detectable stars, not the change in view-point! Does anyone have a good picture of the sky from the Moon for us to solve?
- Here's one from the Cassini spacecraft. The foreground body is Saturn's moon Enceladus. Job
An image with too few detectable stars; it is in the UV, so even the stars that are there may not be in the standards catalog.
Galaxy in the way! This image is large enough for us to solve, but because the galaxy takes up so much of the solid angle, there aren't enough bright stars in common between the standards catalog and the image to nail it.
- update: solves
Source detection goes awry; some of the stars that "should have" been detected are saturated; others may be lost to the confusion limit.
- As with many of our failures of this kind, when binned down 2x2 this image solves
- update: solves without binning-down
Too much camera distortion:

Images that should solve but don't

Full-size fails ( http://live.astrometry.net/status.php?job=alpha-201006-22378084), half-size works ( http://live.astrometry.net/status.php?job=alpha-201006-04056041) but tweak doesn't!

False Positives

The goal is for the system never to have a false positive, so these are very bad. Please add any new false positives you find here. As the system improves and they go away, remove them.

No Longer False Positives

The following images/jobs at one point caused false positives in our system. No longer!

Our first true false positive
- the multiple images of the Moon line up with multiple "standards" created by a spurious diffraction spike in USNO-B1.0; we might not have noticed if it weren't for the fact that the Moon never gets to Dec>29 deg!
- update: NOW IT JUST FAILS
