center of KDG 73

Similar to #23, should the center of KDG 73 be re-evaluated?

Similar to PGC 725719 (#23), the center of KDG comes from the LVG. I suspect that a number of galaxies with centers from pre-Gaia astrometry might have some issues.

My by-eye center (red) doesn't look to exactly agree with either NED/Hyperleda/LVDB (yellow).

.

Do you have an updated suggested center? Or any literature that you know of?

Thanks @apace7. I have no specific references at the moment, but the 'Coordinates' tab in NED gives quite a few references--

Of all the updated centers, this is the one that I'm not 100% happy with. The blue dot is the updated center, red is the previous LVDB center and yellow are other literature measurements. The blue circle is the average of two of the yellow positions.
