Abstract:
A total of 1067 speckle observations of 345 binary stars are
presented. Of these, 161 are double stars first resolved by Hipparcos,
17 are resolved for the first time in the observations presented here,
and 21 are stars previously discovered by our program and reported in
earlier papers in the series. In 947 cases, a magnitude difference is
reported along with the relative astrometry.
Description:
For all observations discussed in this paper, the RYTSI optics package
and the imaging CCD were mounted at the Nasmyth port (the so-called
"WIYN port") of the WIYN Telescope, between 2001 Jun and 2006 Jul.

the format HHMM.m±DDMM. See Cat. B/wds
Note (2): Observation flags as follows:
a = Quadrant ambiguous, but consistent with previous measures in the
Fourth Interferometric Catalog
a? = Quadrant ambiguous, but possibly consistent with previous
measures in the Fourth Interferometric Catalog
b = Quadrant ambiguous, but inconsistent with previous measures in
the Fourth Interferometric Catalog
b? = Quadrant ambiguous, but possibly inconsistent with previous
measures in the Fourth Interferometric Catalog
c = Quadrant is inconsistent with previous measures in the Fourth
Interferometric Catalog
c? = Quadrant is possibly inconsistent with previous measures in the
Fourth Interferometric Catalog
