Abstract:
Five hundred thirty-one speckle measures of binary stars are reported.
These data were taken mainly during the period 2008 June through 2009
October at the WIYN 3.5m Telescope at Kitt Peak and represent the last
data set of single-filter speckle observations taken in the WIYN
speckle program prior to the use of the current two-channel speckle
camera. The astrometric and photometric precision of these
observations is consistent with previous papers in this series: we
obtain a typical linear measurement uncertainty of approximately
2.5mas, and the magnitude differences reported have typical
uncertainties in the range of 0.1-0.14mag. In combination with
measures already in the literature, the data presented here permit the
revision of the orbit of A 1634AB (= HIP 76041) and the first
determination of visual orbital elements for HDS 1895 (= HIP 65982).
Description:
Speckle measures of the binary stars presented here came from
observing runs using two different optic packages (the Differential
Speckle Survey Instrument, DSSI, or the RIT-Yale Tip-Tilt Speckle
Imager, RYTSI) and two different detectors (EMCCD or CCD) in different
configurations during the periods of 2008 June 20-22 (RYTSI/1EMCCD),
2008 September 12-13 (RYTSI/1EMCCD), 2009 June 11-13 (DSSI/2CCSs),
2009 June 14-16 (DSSI/1EMCCD) and 2009 October 2-7 (DSSI/1EMCCD).

Note (1): Identification as below:
HR = Harvard Revised, Cat. V/50
ADS = Aitken Double Star Catalog (1932ADS...C......0A 1932ADS...C......0A)
HD = Henry Draper Catalog, Cat. III/135 and Cat. III/182
DM = Durchmusterung (Cat. I/108, CPD; Cat. I/114, CD; Cat. I/122, BD and
Cat. I/119, SD)
BD-29 958 is a misprint for BD-20 958; corrected at CDS.
Note (2): Twenty-seven objects have no previous listing in the 4th Catalog of
Interferometric Measures of Binary Stars
(Hartkopf et al., 2001AJ....122.3480H 2001AJ....122.3480H); we suggest Discoverer
Designations of YSC (Yale-Southern Connecticut) 141-167 for these.
Note (3): Of the secondary star relative to the primary, with North through East
defining the positive sense of PA.
Note (4): Note as follows:
a = Quadrant ambiguous.
b = Quadrant inconsistent with previous measures in the 4th Catalog of
Interferometric Measures of Binary Stars (2001AJ....122.3480H 2001AJ....122.3480H)
c = These measures were previously published in Horch et al.
(2011AJ....141..180H 2011AJ....141..180H), but the incorrect plate scale was inadvertently
applied. Therefore, the values here should replace those.
d = This measure was published in Horch et al. (2011, Cat. J/AJ/141/45) as a
non-detection; a reanalysis of this observation gives the values listed
at low signal-to-noise ratio.
e = This measure was published in Horch et al.
(2010, Paper VI, Cat J/AJ/139/205) at a separation of 0.131 arcsec;
a reanalysis shows that result to have been in error. The values here
should replace those.
