Notes. It is heavily contaminated on the WISE images by a bright neighbor, and the reddest channel is omitted because it is not useful for a position measurement. The uncertainties are 0.45 arcsec for DSS1, 0.33 arcsec for DSS2 Red and IR, and 0.59 arcsec for DSS2 Blue (Mickaelian 2004), 0.06 arcsec for 2MASS (Skrutskie et al. 2006), 0.15 arcsec for WISE (Wright et al. 2010), and 0.015/0.010 arcsec for SofI, along RA/Dec, respectively.
