Properties of the nucleus

RA, Dec [deg]171.9656, 56.8551
offset [arcsec]0.93

The nucleus was not well modeled by Galfit. However, the coordinates were either: (a) extracted from Galfit if the model was centered, or (b) determined manually with ds9.

HI Data

No HI data was found for this dwarf.

Globular Clusters

No globular cluster candidates found within 70.25 arcsec (5*Re) of the dwarf.
