UKIDSS artifacts
-
Recently the UKIRT Infrared Deep Sky Survey came out for zooites to classify, and with it- a huge amount of camera errors. This page is an information page to identify and report artifacts. Post any new ones not included already in this list, please! 😄
Discovered so far:
Pixolated core
caused by: Bright center, unknown cause.
hashtag (put these if you see the artifact): #pixolated
Ring around nucleus
Caused by: Bright nucleus and dimming of the center so that it doesn't outshine the galaxy
hashtag: #ukidssring
odd green/blue ring.
caused by: bright star being reflected in images far away.
hashtag: #ukidsshole
Caused by: Satellite traveling across the image and causing a rainbow in Infrared light.
hashtag: #satellite or #satellitetrail
no central object
caused by: centered image nonexistant in SDSS, making the UKIDSS image go into the wrong location.
hashtag: #SDSSmismatch
odd cloud near galaxy
caused by: unknown
hashtag: #ukidsscloud
linear/squarish green dots
caused by: pixels glitching?
hashtag: #greensquare or #greendots
Hope the list was helpful and will help you decide what to classify next time you co,me across a UKIDSS image 😃
Again, if you see other ones or have a question, please post below!

how do you embed images in here?
Use the 'image' icon, to the right of the 'code' one!

Thanks for the help Jean! Thanks elisabeth! 😄
By the way, could you feature this so that zooites looking for the bugs can be able to find it easily?
