Observer was copied from the image header of the fits file, acquired with IRSA. Exposure time is the average exposure time from the image header.

The UKIDSS source UGPS J185108.03-004448.6 could alternatively be a possible host of AT 2004iv. I can't rule out this possibility, as there are only 2MASS images to compare. On the other hand the detection of the UKIDSS source fits the date between the spitzer IRAC and MIPS detection of the transient. https://wis-tns.weizmann.ac.il/object/2004iv

The transient was first discovered by the volunteer Julio Albornoz in the Milky Way Project (here: https://www.zooniverse.org/projects/povich/milky-way-project/talk/505/209341), which is an astronomy citizen science project. Spitzer MIPS [24] show a source at the same position from 2005-10-02, but WISE images don't show any source at this position in 2010. Grace Wolf-Chase from the Adler Planetarium took part of the discussion as a researcher. Many thanks to Richard Nowell and Alexander Jonkeren for helping me with APT.
